Joel McNamara wrote a really thorough review of the Garmin Forerunner 201, including a comparison with the Garmin Geko 201with the Forerunner.

This is a well-researched piece by someone who definitely shares my interest in fitness gadgets. Joel has also pointed out a product and a service that I had not seen before that relate to adventure racing. EndlessPursuit is a value added reseller of GPS and heart monitors that offers a service integrating information from the two in a way that allows better performance analysis. (EndlessPursuit also helps you exhibit your training to friends and family.) TopoFusion is a $40 software product that lets you integrate GPS tracking information with map data from the Microsoft TerraServer.

Included in this review are size comparisons with Timex Ironman wrist watches and late-model Polar HRM receivers, and Joel's list of "cool" and "iffy" features. He seems to agree that this product has some minor satellite lock issues during exercise, as I suggested it might in previous articles. He's also not really a fan of the Logbook software, at least version 1.0.

As I said, a great review. He includes the first screenshots I've seen of the Logbook. That alone makes his review worth checking out.
