I bought the vuelta zerolites on that sale. They're my first fixed gear wheels and the low price is what helped me finally make the leap. I've been riding them for about a month. They work fine, were delivered true and with uniform tension (at least by ear, according to the pitch of each spoke).

That said, it was an impulse buy and I already wish I had done a little more research and bought better wheels. If I had not liked the feel of riding fixed gear, I probably would be happy that I hadn't blown much money on the wheels. However, I do like it, so I have a touch of buyer's remorse. 50% more up front cost probably would yield a 100% better wheel - with sealed bearings and stainless spokes, better eyeletted rims, etc.

Bottom line: Go with some of the alternatives recommended above. Take another month to save up and get a pair of wheels that will stand up better and longer.
