Well I found a online retailer that matched a price of another retailer so for $35 I bought a gunmetal K-Edge for the incoming Edge 810. Now to sell the 705 to someone wanting to enter the GPS world of cycle computers!
After researching this:
Raceware is the best, but it's hard to get in the US(super light and mounts as good as k-edge and garmin)
K-Edge and Garmin are pretty much a tie(mount at same height as stem, but a little on the heavy side)
Barfly and SRAM are the worst(mount higher than the stem)
I bought the Garmin, b/c of price. It's also a couple of grams lighter than the k-edge if i remember correctly.
K-Edge, it comes in red.
Really happy with my Bar Fly 2.0, the Garmin is now flush with the stem, and there is a positive click when locking it into place.
