I figure that instead of continually sinking money into DustOff and similar products, it would be smart to invest in a small air compressor. My initial search for such a device was a bit overwhelming: there seems to be literally hundreds of different manufacturers and technical specs. I'm hoping that someone here can point me in the right direction: I'm mainly concerned about buying a reputable brand and I'm unsure about the quantity of "pressure" that is required to do a good job of dusting out a PC. I should probably mention that I'm a water cooler, so I need something that can easily blast out the dust that builds up between the radiator fins. I hope that this is enough information to work with, but let me know if there are other concerns that I should be aware of. Thanks in advance.
