I would go to Home Depot and show them the Lowes offer for free tools. Then get the Husky with matching tool offer from them or walk. First thing I would want is highest SCFM rating. Then low maintenance, then added tools, then dB level.
I was under the impression that SCFM is a volume rating and is more important than PSI. It allows for better torque and if you intend to use impact tools this is important.
I would also compare whatever you lean towards to a comparable Craftsman just because Sears is good about generous free tool kits with comps that size.
