I would absolutely buy the Secteur with confidence. I think the rear wheel is 32spoke. Correct? If so, all you need to do is buy a front that is 32. Maybe if you're over 325 you might want a 36rear but even then you can easily find a good set of 32/36 wheels for well under the price he quoted you. There would be NO point in having just the rims replaced at that cost. That was a rip-off quote. If the existing wheels are built well, I'd bet they would work just fine. If you road them for a while and broke a spoke in the first few months then you might want to get a sturdier set of wheels but a properly tensioned set of wheels 28/32 would probably do you just fine. I'll admit I would not bomb down big hills with them so yeah...it might be good to buy a second set of wheels but just do so from a catalog house or ask what deal the dealer would give you on a new set, but definitely do NOT pay that kind of money and still end up with the same hubs.
