I need a good compressor for my new 625sqft 2 car. I would really like something that is as quiet as possible and would allow me to run a DA for some hobby paint and body. I definitely want to go with an upright design and an oil less model. I see both single and dual piston compressors. I figure I can spend around $500-$1100 on the compressor. I want to stress that quiet is best and I can run either 110V or 220V as I have both wired up. I do fairly intense weekend wrenching on my Bronco and Lightning. I would like to use air hammers, and a stout impact as well. What are my best options here? I would prefer to buy new vs going the craigslist route because I'm leary of used electrical products. Thanks!
