My LBS sells the trainers for home for about $250 (cdn) for the lower end ones and up from there. They are a great way to keep in shape, however, I found that when I took an indoor spinning class, I was much more motivated to ride. I had it scheduled weekly, and there was always someone there to "push" you to go hard.
I do know quite a few people that have the one for your home, and they do love it. Good luck, and congrats on your accomplishments this summer!
