Greetings,
About 4 months ago I purchased direct from Wahoo, a factory reconditioned Wahoo Kickr SNAP, wheel on trainer. You may want to check the Wahoo website for a reconditioned model, the one I purchased was significantly less than a new trainer, and I recall there was also a sale going on when I purchased mine. So far it has worked flawlessly.
On the recommendation of a friend, I did purchase another rear wheel, cassette and trainer tire to use on the bike when on the trainer.
