Thank you Oakleaf and Zoom-Zoom for the Garmin info. To clarify...I was asking Zoom-Zoom about the 305 Forerunner. I liked the fact that the Forerunner has a smaller footprint than the Edge. Although, there is a fella on the triathlon forum that I frequent, who is selling a slightly used 705 Edge (complete package with maps, HRM, both sensors, etc.) for $300. That is almost a deal I can't pass up...until Oakleaf mentioned that the cadence sensor isn't waterproof...I'm not sure I want to drop 3 bills for something that will require me to remove the cadence sensor, every time I think a raindrop might fall from the sky. Call me lazy, but that sounds like a MAJOR PITA...and something I'd rather not deal with.
