a pedal assembly is going to run you about 2~3 hundred easy, and well north of that for one that's been rebuilt. so just know that going in. there's a few kicking around on flea-bay and a wanted ad here might unearth one as well.
the flywheel is pretty standards. brewers has reconditioned ones reasonably priced.
