You all are really stretching my resolve to wait just a bit before making another major purchase! It really is a cool and useful toy, isn't it! Thanks for your answers. It's good to know I get two mounts. And I'll be sure to tell my friend about the rebate, and maybe use it myself!

Cadence is something I use all the time, and find it very helpful. I also need it for the winter months on the trainer. It's one of the reasons I like the 305, it's has everything I "think" I need. bikerHen
