I want a little air compressor for basic garage use. Not gonna run any air tools, I just want it for filling tires, blowing dust off of stuff, etc. Needs to be pretty easily portable so I can take it out to the driveway or upstairs to the deck to blow the dust off before refinishing, stuff like that. I do want a real shop-size compressor eventually but that's not gonna be in the cards for a while. Any real reason to go with more than just the basic 3 gal HF one?
