Air compressor alternative?

[suicideneil]

Have you considered picking up an old divers air cylinder? They come in handy sizes ( 3, 5, 7 & 12Ltrs ) and can hold ~2,000psi. Just stick a suitable valve and hose assembly on if one isn't included & attach a suitably pressure rated 'gun' to the end of that = high pressure dust blower that lasts forever...?
