There's nothing in that size range that can be called, "really good". In that size range, they are all oilless, so basically disposable.
Get up at least into the 5 hp 60 gallon range, and you can now start to get something decent. And an upright 60 gallon really doesn't take up any more floor space than a 30 gallon toy.
And you'll probably find that having air available is addictive.
I agree.
I just bought a 60 gallon vertical model with a 1,800 RPM 5 HP (running) motor made by Eaton Compressor, aka AirBase, aka Polar Air. I bought this model because they had it listed on Amazon so it shipped free, and MT is a long way from Dayton, OH where it is built. I wanted a quiet unit and 5 HP units with 1,800 RPM motors are becoming difficult to find.
Eaton Compressor makes many compressors for others who sell them under their own brands, e.g., Northern Tool, EMAX, etc. They usually do not sell on Amazon but this unit was on Amazon and I couldn't pass up the free shipping, as the folks at Eaton Compressor told me that shipping to MT would normally cost over $800.
This is the third unit that I've bought from Eaton Compressor in the past 15 years or so and all have been good units. They do not make small units or 110VAC units, though.
