If it sounds like I'm talking from personal experience, yeah...

I second the craigslist idea.
I've gotten all sorts of parts off of craigslist, usually for dirt cheap. The only bad experience I've had was a $15 unicycle I bought. And frankly it wasn't even that bad...a bracket was missing that stabilized the wheel, so it's at in my basement for the last 6 months lol.
Back on topic. It really isn't that big of a project. I got a set of 9 speed shimano sora brifters for $25. All this stuff is out there, if as mcours2006 said you're patient, and know what you're looking for.
