anyone see the ad in runner's world for the new watches? Forerunner 405 CX - looks like the 405, but dark blue Forerunner 310 XT - the same as the picture from the last post, say's this one is "swim-proof and extended battery life for multisport features" mmmm now the dilemma is which one to get? i still have a 305 and didn't get the 405 because it worked fine. Guess I'll wait for some reviews. and just found this.... http://www.beststuff.com/fromthewire/garmin-makes-every-calorie-count-new-forerunner-405cx.html
