this is all good advice and probably what you should do, but i personally am riding wheels that i did rim transfers on over a year ago and everthing is fine. granted, i don't weigh much and the previous use of the spokes was only on the track on tubular rims. if you are broke, then i would say maybe the transfer would be fine. just get a rim with the same ERD as veggiemafia said, tape it to the old rim, and transfer one side of the hub's spokes at a time, and be careful with your work. then have a pro tension and true them if you are not confident with it. good luck!
