Since minimizing cost was a big factor in the OP's other thread, I would recommend this for the off-season. Add GPS if desired in the spring, and hopefully resell the Cervo then.

The PowerTap will send speed and virtual cadence. Virtual cadence might be okay if your cadence is stable, especially on a trainer, which has smoothly varying resistance.
