Just got a bontrager node 2 for christmas. Originally I asked for a cateye v3, but my lovely wife said that someone recommended the node, so thats what she got. Anyway after using it, its great and im really happy with it. The thing is super accurate including the altitude. Its easy to set-up, and easy to use once you get the hang of it. The only downside is that you have to buy the sensors separtley. Im not sure why, but this thing is kind of hard to find online, and there are not many reviews, but I would recommend it.

Good choice i have the V2c model and have had problems with it and i heard from cateye that it is a common problem and bothe the V2c and V3 models are the same, the issue that i had was buttons stopped operating could not switch screens very frustrating. I also like the big display on the node 2

The Node and the sensors are ANT+ devices - you can also use them with the Garmin 500/800 - good choice

Just got a Node 2 and Duotrap pickup for my wify's Madone. Very nice, but expensive. Since they're Trek, you basically have to get them through your Trek LBS since Trek prohibits mailorder of their stuff.
