gvhbikes.com has a sale on American Classic's right now. Again, warranty, think about it.

though I'm pretty sure you are advertising after your last response.

P.S. the cheapest custom built sub 1350 gram wheels are about $620 including shipping according to those that I've contacted. Not a terrible price, and probably worth the ability to tune to rider needs, but still, cost more than American Classics.

Oh and Dura Ace cassettes can be had for $115 fom pro bike kit.
