Hmmm...stripped out some Pro-Line rims? That is not unheard of, but does not happen often.
Before getting another set of rims, you may want to solve the problem that caused the stripping of a decent set of rims in the first place. Otherwise, any suggestion made might lead to the same end result.
In the meantime, TRAXXAS T-Maxx stock rims are pretty ruggid, RPM rims are pretty ruggid, the Pro-Line rims are tough (which is why I am surprised you stripped them), IMEX makes some nice rims, Hot Bodies has a few also.
