I use the Bontrager Trip 3, and am very happy with it. I REALLY prefer computers that mount on the stem rather than the handlebars, and this one goes either way. I've tried wireless and had poor luck, and this one has a nice hefty wire that I worry less about than I did with my older computer with a tiny wire. The Temperature reading is a nice feature, and other than that it does what it's supposed to and doesn't get in my way.
