they're pricey for what you get, and I've read more than enough bad reviews of Trek's digital wireless computers to make me buy something else. If you're looking for something in that price range, the Cateye V3 is good for the money.

As for pedals, I don't think there's a significant enough difference between the 105 and Ultegra pedals at PBK to warrant $50 more for Ultegra. I have Look Keo Carbons ($125 at PBK right now) and am happy with them. The plastic cleat does seem to wear faster than the Shimano cleats, and they get scuffed more than 105 pedals though.
