once you add in shipping it's pretty much the same cost as getting the same wheels at a LBS (at least in NYC). It's the exact same set I've used. Pretty durable. Had to do a little retensioning to the rear last night, and the factory locknuts backed off by themselves. Torque them up when you first get them.
BTW. I always wondered how much these things weighed. Good Lawd they are heavy. I'm just used to sub 1600 gram wheelsets I guess.
