I just picked my 2014 7.4 FX up. It was a great ride home!

Now a quick discussion on bike computers. I had originally bought the 2015 7.3, so I was going with the DuoTrap + Bontrager 300 setup. However, the 2014 isn't DuoTrap compatible, so I told the LBS to put a Speed + Cadence computer on. They chose a $50 CatEye. However, they were unable to get the cadence to work, likely due to the distance from the frame to the crank. I had them remove the CatEye, and am now looking for a computer.

* The 2014 is Speedtrap compatible, so that seems like a good solution for the speed.
* Does anybody have a working cadence sensor? ANT+ preferable.
* I am stats geek, so I start Strava everytime. I realize my phone doesn't talk ANT+. However, any recommendations that won't break the bank for a computer that can talk to the ANT+ sensors, and Bluetooth to my phone?
