I bought one of Dewalts 30 gallon 120v/240v compressors when I first moved into my house. I wasn't wired up for 220 yet and figured it would be big enough for all my needs. It has worked GREAT. The only place it struggles is with painting....I painted my car this winter. It kept up applying the color just fine until but when we got to the clear coat and it had a hard time keeping up which ended up creating more orange peel (just had to wet sand more). Its been a great air compressor (Going on 6 years) and I'd buy another dewalt, but I'd def get a 60 gal next time. Before I paint my next car I will have a bigger air compressor, but who knows when that will be.
