re: Air Compressor-- oil lubricated or oil free?

Have a friend who does trim carpentry, used to run those red Porter Cable pancake compressors. 2 - 3 trim guns (with leaky hoses/fittings) doing high-volume work all day and those compressors would last a few years while getting the crap beat out of them. Usually failed because they were dropped, left out in the rain too often, or fried by a power surge than just wearing out the piston seals. They can be rebuilt fairly easily too. Now he runs one of these and it's held up pretty good. Definitely need to run a quality synthetic compressor oil for cold days and heavy usage.
