For the OP, for moderate home use you probably don't need the extra expense of a 3-phase compressor. It will run more efficiently but you will have to incur the extra expense of having special wiring run. Also these compressors are generally more expensive as they are for industrial use. My Husky 1-phase runs great, and all that's needed is a 220/240V outlet. I think it pulls 20 amps.

A 2-stage compressor may refill quicker, again they are more expensive. A 2-stage basically puts the compressed air thru a second cylinder to compress it further, so it pushes more air into the tank, hence most 2-stages are 2 cylinder. The 1-stage Husky that I have was about $850, with 3 cylinders (1-stage so all 3 pump directly into the tank) it does very well. I can continuously sandblast w/ the regulator set at 80psi and it will refill and shut off while I continuously draw air from it. Plenty good for 99% of home mechanics. I think this particular model is a great value for what you get. Most comparable compressors are north of $1200.
