The canned air is really expensive, you end up using a half a can on a PC. If you do the compressor, make sure you put a regulator on your blow gun: 80-120 psi of air coming out of a blowgun is capabable of blowing components off the circuit boards along with the dust. The compressor is also very useful for blowing out the air conditioner coils every year, as well as the refrigerator coils on the refrigerator. Doing just this will pay for the compressor in a few years in energy savings. Ted
