I have had the same positive experiences with ebay storefront sellers. My buddy and I both bought new bikes from one particular storefront seller. I paid $495 for a new bike with Tiagra shifters and 105 derailleur. I figure this is 1/2 what I would have paid in a shop, even if I got it on sale. The catch: had to assemble it myself. Not a problem for me though, as I do 99% of my own work anyway.
