I am with the buy new crowd. if you are having difficulty and dreading overhauling the hubs building new wheels around these hubs may be a bit much for you.
last winter I had several pair of wheels built at a cost of about $250 to $300+per pair. I wanted very specific wheels though, old school tubular rims on shimano cassette hubs, with radial or crowsfoot lacing. unless you have such needs you may be better off buying new.
