Last time REI had one of their sales, where people get a 20 % off coupon to use as they see fit, I got a nice pair of Giro shoes with carbon fiber soles for $160. They had SIDI Dominators, too, but not in my size. After trying on all of their high-end bike shoes, the Giros fit me best.
They're having another one of their sales now. FYI.
