Never used one, but.
I have found with cheap guns they usually go alright, for a little while. They just bugger up a lot faster than good ones.
So long as you clean it out properly every time you use it, and dedicate one tip for primers and one for top coats, you should be fine.
Im guessing the third one would be 2mm.
2mm would be good for Acrylic primers and perhaps very very thick 2k primers and also clear lacquers over furniture etc, 1.7 good for 2k primers or Acrylic top coats and enamel top coats, and 1.4 good for 2k top coats, listed what to use for all paint systems as i dont know what you will be using.
I doubt it would frOck up in the time it would take to paint one car, you might get two out of it. If you only use it now and again and clean it PROPERLY after each use it will probably last forever. Biggest problem is consumable items are usually hard to get for no name type guns, like rubbers seals etc.

I bought a suction feed one with a 2mm tip and sprayed my VK in acrylic, no complaints. Didn't pay that much for it though, was only $100 or so - if it ever needs parts then I go buy another and get a nice clean one

go with cheap throw away models ben i reckon unless you want devillbiss or iwata then go for the magical name in guns called THE STAR model cheap as chips and good performance to get you out of trouble all depends how much you use it cheers billywest i got a bit of an idea how to spraypaint and i usually if you got no knowledge go and look at the tin of paint you want to paint and they will tell the kind of gun to use and what mm to use aswell cheers or just ask behind the counter you might get sum good advice iwata start from 500 bucks but i am not sure i will find out the mm on the gun at work 1.7mm sounds write to me anysmaller and your going into touch up guns and bigger and you go into industrial and spray putty guns like a thicker liguid hope i have helped 0.8 sounds like a touch up gun ben

You wont buy the tips form a panel shop.
Usually there worth more than the gun to buy as spares so when the tips become oval throw the lot in the bin and start again.

I bought a cheap Arlec gun from Bunnings a couple of years ago.
It had a nylon sorta washer to seal the air cap.
When I finish with a gun, I clean it, blow some thinners through it, dismantle it, put some thinners in the pot and leave the cap, nozzle, jet and needle soaking till next time.
I went to use it last Thurs and couldn't find the nylon washer anywhere. I think the thinners ate it?

I hope you made a new one from a weetbix box.

Bare in mind that $200 is not that cheap for a spray gun. You can get them for $50 and up.
I've got a knock-off of an Iwata W-400 (a popular professional quality gun) and it's pretty much an identical replica anodized in a different colour. HVLP Gravity feed, plastic cup (actually a good feature!), three different tips, nicely constructed and finished. That only retailed for about $150 I believe (it was a present from a good friend). And I've painted a few cars with it, lend it to different mates quite often etc. Has done everything that I want it to do basically, I'm sure you can do a shitload better and I probably don't even realise how good a 'good' gun is, but for what I use it for, it really is ample.

We purchased a SCA Blue handled HVLP gravity feed on sale for $35,
it is the general dogs body workshop gun,
we have used it for GMH Black on lots of parts,
and used it for other acrylic single pack paints,
it works fine for the purpose.
Disadvantages over my Devilbiss GTI Pro,
SCA has narrow fan, ie can't adjust it very wide,
spray pattern is quite rough using 2k paint,
does not spray out very smooth finish,
fluid and air adjustments not very accuate,
if you turn the air in, then back out,
it is hard to get where you want it at times.
But as the GTI Pro cost $499 and the SCA was $35,
it does a good job for the price paid.
Basic Gun Cleaning 101.
Clean your gun up with gun wash, or general purpose thinner,
both are similar in price, around $25 for 4 litres,
the gun wash is recycled thinners and paint products so can contain contaminates,
so can smell really nasty, I prefer to use GP thinners,
GP Thinners do not smell as bad,
and is less harsh on your skin if you spill it on you accidently
These products can be purchased from SCA or repco or similar.
Rinse the paint container of the gun first, discard waste in a metal container,
then add more thinners and flush the gun through until the thinners runs clean out of the tip.
Easily done with a gravity fed gun,
for suction feed guns, attach air line and blow the thinners through the gun.
This usually the most you need to clean a gun.
If the paint was in the gun for a while,
you might need use a cleaning brush to clean the paint cup,
and take out the needle and remove the fluid tip,
and clean up with the brush that was supplied with the gun.
Reassemble and flush with thinners again as above till it runs clear.
Replacement tips and needle kit, get from supplier of the gun usually.
Also wipe over the outside of the gun to remove and excess paint on it,
and any excess thinners that you may have spilt.
Cheers
Chris.

To reply to original post,
Ben,
they are fairly well made,
good to use, would not stand up to daily use,
especially if put though a gun wash machine,
that destroys the seals really fast.
But as weekend use tools, and hand cleaned gun not machine cleaned,
can give a good finish, need a bit of patience to set up,
to get it to spray to suit you spray technique
and need to make sure use good overlaps when doing panels.
for the price of the guns you can achieve good outcomes with a bit of patience.
0.8mm is used for small touch up repairs, or good for using under guards.
Cheers
Chris

Some people , including myself usually get away with just flushing the gun but and especially with 2k I pull the gun down every time and clean it out thoroughly, had a few blockages, not what you want in a $500 gun.

I think i paid around $80 for my gravity fed spraygun from SCA.
It has done a lot of work, but i'm rather pedantic about cleaning.
Infact... it was so good, somebody borrowed it & it never came home.
