I bought that set on sale too, and all that is left is the crown stapler. Probably because i hardly used it. The compressor died real quick. Very disappointed in PC.
In this new age of LiIon batteries, if you're going to use the nailer a lot, I'd consider the rather hefty investment of a cordless finish nailer. It is a nice thing to not drag that air hose in and around your freshly made cabinet. Yeah they a bit bulky and don't fit in smallish areas, but the benefits are there. The Hitachi cycles almost as fast as an air gun, but, if using a finish nailer, it never a race to shoot nails.
