Need some new fitness gadgets...

So I have a GPS on my bike, an older 12-channel eTrex. It has it's problems. It looses signal too often in the city so my stats are off a bit (I've was at an elevation of -5 feet) for a mile or so today. So I'm looking for new gadgets to use for this.

So far I've come across the ANT+ system by Digifit and I think it does exactly what I want. Since I use my iPod when I ride anyway, it's one less gadget to carry around. Amazon sells it for ~$80. Since ANT+ is a relatively open system, there's multiple vendors making gear for it:

• Adidas sensors and devices (ANT+)



• CycleOps sensors and devices (ANT+)



• Garmin sensors and devices (ANT+)



• Quarq sensors and devices (ANT+)



• Spinning® / StarTrac



• Tanita weight scales (ANT+)



• Timex sensors and devices (ANT+)



• Wahoo sensors and devices (ANT+)

Plus a host of others. So I can add a Garmin speed sensor and a heart rate monitor. If I go to the gym I can get the info from the StarTrac treadmills. Not sure I'll go as far as the Tanita scales though.
