do I need an air compressor?

[greatmaul]

Hi, I really want to give my bike a tune up but so many of the things (minus the valve adjustment which I'm really just not ready for) seem to involve compressed air. I'm thinking mainly of cleaning the air filter, of course, and blowing out the area around the spark plug because with my luck a big lump of dirt or a dead dragonfly is sure to drop in that hole as soon as I get the plug out.

Does everyone just have an air compressor lying around? If so, is it a big one? because I've looked at them and they're a bit pricey but you can get the tiny ones that can't even run an air ratchet for about $99 on sale. I know the tiny ones would blow the air filter out and the spark plug area, but I'm just wondering how other people do it.

I don't think the ones at the gas station actually blow air out unless they're hooked to a tire.
