lmao! i run those same exact wheels, that i got for $330 shipped from Performance back in 2008ish, and they still roll like new to this day. granted, i only ride about 1000-1500 miles a year, i can count on one hand how many times i've had to true them and i'm 230 pounds. i personally love them, they roll great and have the quietest freewheel EVER... lol

i agree with the other here though, that you can find PLENTY of really nice wheelsets for under $500. as far as new vs. used, that depends on you, if i was you i would get used if you plan on keeping them on the bike and new if you plan on carrying them over to your next and newer bike...
