IMO;
I used a LPLV unit from Harbor Freight & I returned it the next day even with the yellow paint splatters on it. Maybe there are better units out there but for the $$ I was very DISAPPOINTED with the air flow to the fender I was painting. The unit in question was an all in one unit, motor & gun.
They have a 100% satisfaction thing, well I had 0 satisfaction. It could have been me also?
But I wasn't going to take the time out to experiment.
I guess you get what you pay for.
I used my regular comp., followed the directions to a T for spraying. Practiced on sheetrock, wood panels & some metal. Got confident & got part of the job done. Now i'm waiting for the weather to break to finish my spraying.
I got some 1/2, 1/3 left over paint from my buddy that he had from some left over automotive jobs & the price was right, $O$ .
A friend of mine that restored a OLD simplicity used a cheap pancake comp., & did a fantastic job. He also bought his on sale at Harbor Freight for about $ 69.00.
All in all i'd stick to an regular air comp., practise a bit & you'll be good to go.
