GEEK’S DELIGHTPaging all data whores! The S625X, which ships with a wireless speed sensor that mounts on a shoe, lets you program and track a seemingly infinite combination of complex workouts. (Wireless bike cadence and speed sensors are sold separately, $40 each.) Forty bucks also buys you an infrared PC interface that lets you chart your workouts on a Windows box.
Bonus: The comfy WearLink chest strap works with any cardio machine that packs a wireless heart-rate function.
Bummer: It’s not exactly intuitive to use, and the manual’s a dense read.
