those are a good deal indeed. If you want to go the custom handbuilt route which is perfectly okay, handbuild wheels will last a long time. Then i suggest Sun or Velocity rims. I think mavic is way overpriced, sure they are generally pretty round from the factory but nobody will notice if their wheel is 1mm out of true on one side. Sun rims are an awsome bang for buck, particularly Rhyno Lites which seem to be popular here. Velocity is not so well known but i would say equally good. Their rims are set at friendly prices, and they are at high quality. Their Deep V is super strong. I got my Sun rims for 30 on ebay. And you will also have to replace spokes keep in mind
