I've had an older 9-sp flight deck on my old bike for ~5 yrs now, no problems, great computer. So I wanted another one for the kestrel I bougth this summer (10 speed). There was no way I was paying their suggested retail for a computer, though, might as well just pony up and get a garmin edge.
Some long, diligent ebay watching and I scored the 10-speed computer and wireless wiring harness, brand new, for ~$50 shipped.
