I researched a lot and ended up with the Cateye Strada Wireless. See here:

My spouse has the wired version of this computer and his also has cadence. I don't care about cadence, but I do care about mostly my distance and speed (average and maximum), time, etc. It is very reasonable to set up and I haven't had problems. I was able to buy the small parts kit which allows me to move it easily between my two bikes.
