OK, I want to treat myself to an air compressor. I dont need anything crazy. Dont have a ton of room in the garage. I do want to run the occational impact wrench but nothing much more than that. There are a buch of different brands out there, but what is the big difference and what should I look for? I see the high end ones out there that are big $. Then I see the ones at harbor freight from central pneumatic that I can get for a great price with the 20% off coupon. Has anyone owned one from harbor freight? Obviously I was to save as much money as I can but I dont want a piece of crap either. Little help here! Thanks
