Prices on the Garmin Edge 605 are dropping -- you can buy one plus the necessary Navigator software for just over $300 now. On my site cyclingnewengland.blogspot.com I post the best club rides and tours in New England with links to the ride on RideWithGPS or MapMyRide. From those sites you can download the GPX files for the Garmin Edge 605, 705, and 800, which are the only bicycle computers that have the capability to follow a ride you have programmed or downloaded from those sites.
