I do a lot of PC and laptop repairs. I've decided finally that cans of compressed air are too expensive for blowing the dust and dirt from heatsinks and fans. I'd like to get an air compressor but haven't a clue what to look for.

I've seen some cheap ones at Argos, but judging by the reviews at 100db they'd be far too noisy for workshop use. I don't mind having one which can charge outside but It needs to be kept and used indoors.

Does anyone use a compressor, or know one they could recommend?

Thanks,

Ben.
