. I looked into buying a bulk amount of compressed air at Costco since I do a fair amount of rebuilds for friends and family. Long story short I bought a cheap compressor from Screwfix (was on a special £50 with free accessory pack, currently not on but I think they are changing the range soon). I reasoned over time (next 10 years) I would save a fair amount of money since compressed air isn't that cheap and will only get more expensive. As long as you are sensible you wouldn't have a problem (not too much pressure or get too close, make sure its oil free and/or doesn't have an inline oiler). You may be surprised the other uses you can find. plus I just like my power tools 

i was thinking along the line of paint brush or compressed air can
