I have a Kobalt 60g compressor, although it is on a 240 circuit i ran. Pretty quite and cost wise was about 420 bucks i believe plus a little more for the plug and wire, and circuit. Also you going to have to plumb it up with will run at least another 120.00. All the 120v ones were really not enough to keep up with my IR CFM requirements for my 1/2 and 3/8 impacts and things like die grinders. I didn't like the idea of it constantly kicking on and off so much. For the cost of 120 vs 240, not much difference and u get a much better compressor IMO. If you have a circuit available, i would go with that, I couldn't afford of justify the cost of a 2 stage unit.
