I just bought a front wheel from thorusa because he was going out of business. Now that he's gone where else in the US can one find folding bike parts? As far as the question here I will say that buying a high quality wheelset is the most important upgrade you can make to a bicycle. Last year I upgraded my mountain bike wheels and it has made me a much better mountain bike rider. My confidence has gone way up and for the first time I feel in control of the bike. If it's not a question of money than I'm of the opinion go ahead and spend the money. I might try looking at Modernbike.com for a cheaper wheelset. They have always been reliable for me.
