I'm looking for a miniature compressor/pump to help clean out my PC since i'm running into issues with the brand of canned air that I use. The brand I get seems to be purposefully altering the pressure of the can. It's not getting the dust off my components and it's quite the annoyance as of late. Anyone know of a good mini-pump I can get that will help me out? I can't spend hundreds of dollars on one, but I don't find a $50 to $120 pump out of the question.
