Good luck on the hunt.
+1 if you are only starting with a frame its nto too hard to find a cheap Trek Schwinn etc bike that will be good for your project. You could even put and ad on craigslist that you want just a frame and say you are on a budget. Someone might give you a frame/bike. I have a couple frames I need ot put on Craigslist since I don't plan to do anything with them.
