Still shopping for a compressor for home use (anything from barad nailer to 4 tire changing impact wrench, to maybe light spray application) and am stuck between a good twin stack (Rigid 4.5 gallon OF45150 ), campbell hausfeld 15 gallon, Husky 15 gallon with campbell hausfeld tool combo or now a 15 gallon Porter Cable (CPF4515). Is the ridgid OF45150 as good as they say and can it handle the occasional tire change. Can anyone comment on the others or have any insight on a portable compressor under 20 gallons for the average tire rotating woodworker?? The PC has one of the highest SCFM's as does the smaller Ridgid?? But any help would be great. Also Home Depot sells a Husky air tools set. Is it better quality than basic Campbell Hausfeld tools??
