I already have a 135 PSI compressor and a set of 3/4" sockets, so I'm already more than half way to a solution. All but one of the reviews written about this one were very positive, but if anyone has one and has a complaint, I'd like to hear it.
you don't need a 3/4" impact to take blades off, get a 1/2".
