I have a question for you... I'm thinking about taking a bmx and converting it into a higher, more-upright bike similar to a mini velo, like this:

This bike, however,would have brakes and a front derailleur (I think a 2 speed bmx with a fd and tensioner is possible)

can anybody recommend a certain brand/decade of bmx to look for on CL and ebay? Something that is aluminum or 4130 cromo... decent BB heights for 170mm road cranks... and not too expensive? Budget for this project is around $100... conversion parts are going to be at least $35 of that.

Thanks
