I purchased a set of 10" Campys a couple years ago that were straight but cosmetically poor. I followed the restoration precedure linked by #5754, including plastic bead blasting (about $50/rim), annealing and painting with Eastwood Argent Silver. In addition, I filled the curb rash with Lab Metal. The results are rims that appear new.
Below is a picture of the final result. The decals and center caps are offered by several suppliers.
I agree that if your rims are cosmetically acceptable to you, it may be best to keep the original paint intact. But otherwise, it is not difficult to restore them yourself.
