I avoid most of the places you list. Chainlove drives me bonkers, because you have to be there just at the right time to catch a deal. I refuse to get sucked into that sort of thing. Nashbar is like a shady furniture store -- they are always having a sale.

My short list: Jensonusa.com, UniversalCycles.com, Speedgoat.com, ChainReactionCycles.com, and sometimes TreeFortBikes.com.
