Finding one for a bargain price might be a little challenging, but not impossible....Go with what you want and if you're looking for better quality, look for quality material used in the frameset....most companies (mass produced) had a range of quality from entry level 'gas pipe' to fine quality Columbus or similar level tube sets.

No matter what you get, make sure it fits and please do not hack it up and cut things off, so that maybe one day it can be built up with derailleurs and such....! Good luck with your project and post pics when you do it !

Cheers,
Joe
