I had to go wired because my Cygolite front light screws up analog RF wireless computers in close proximity when the light is on flash mode. Apparently you have to go ANT+ digital wireless to keep that from happening. So I just got a cheap wired Bontrager computer and it's been great. I got the next model down from the one with cadence, because I didn't want to run a fat sensor wire down my frame to the rear chainstays. I think it was around $30 at the LBS.
