I'm getting ready to break down and purchase a new air compressor. I've decided that since I don't have 220 ran out to my shop, and I can't seem to get anyone over here to help run it, that I want to just go with a 110 - the portable standup type with wheels. This would suit two advantages. I could use it out there, AND up here in the garage if needed. What I would like to know, is what is the biggest (CFM) compresor available with just a 110. So far, I'm coming up with 6.0 CFM at 90 psi. Any advice?
