I really like BD. yes, I do ride a kestrel (its awesome by the way) but I did not buy it from them.

$400 for a secret sale is probably worth the money. you may need to retension/true your wheels, double check all your bolts for tightness, bearings for lube, yada yada but... the bottom line you're getting a compete bike for a great price. even if you bring it to your lbs for a thorough inspection I'll bet you'll be happy enough overall.
