IMO, the best form of compressed air you can get is a diver's flask. They're probably the cheapest thing per blow as well. I have considered to buy an old one that is no longer deemed safe for diving purposes.
My experience with canned air from the local photo pusher is mixed. Yes' I got both the mirror and the CCD clean, but at the same time I got two big bits of grit on the matte screen. I know for sure they were'n on the CCD or the mirror in the first place, so it must have been shifted around from somewhere else inside the mirror box. If the main result of using canned air is just to relocate grit, I'm not sure it's such a good idea. That's what keeps me from buying the diver's flask too.
