Re: HVLP spray guns
The small touchup gun with 1.0 tip is all you're likely to use for small projects like boxes and such. The 1.4 tip is normal for most base/clears on auto painting and the 1.7 would only be used on high build urethane primers.
You get what you pay for. My Sata MiniJet II touchup gun was $250. I've seen Chinese knockoffs of it at Parts America for about $69. I'd buy one of those before I'd get a $69 set of three pos guns that spit blobs of paint and have no replacement parts available.
But if you must.. those 2 kits look to be about the same except for the extra pressure gage.
