Here's a tip. People pay bottom dollar for used tubular wheelsets. Often a hubset will have a longer life than the rims. You can often find good deals on CL for tubular wheels. I've picked up several tubular wheels off CL for less than what the hub alone might have sold for on ebay. Then either go tubular ( ) or take apart the wheels (polish the hubs while you are at it) and rebuild the hubs with new clincher rims. Obviously, you won't have as many options to choose from, but if you are not picky and don't mind used items, it's a strategy worth considering.
