Not sure about that?

I can recommend these compressors at this price, after looking at a few different types and price ranges these are pretty good quality. The castings, build quality, fittings and metals are far better than all the cheap ones I looked at and on par with the better brands. Obviously early days but they run well, quiet and with a 2 year warranty I'm pretty happy.

The tradetools renegade ones seem pretty good, have also used pilot as well.

Keep in mind even a 15amp compressor can paint a panel but not an entire car, spray paint booth for that ftw...
