great exercise bike

I have a lower back issue, but really like to keep myself healthy. I thought about joining a gym, but I live 45 mins from the nearest gym, and that would be a bit costly over time, and a gym membership varies from 75-100 $.
I have some weights/bands... just needed something for cardio that would work with my back.
I did some searching, and went to many stores when I finally came across the NordicTrack C VR21 Exercise Bike.
Of course I tested out the demo to see how comfortable it was, and I was happily surprised. It also has a great warranty.
The features are great and easy to use, can load workouts, and seat is easily moved to your most comfortable position.
I also read up on every review that I could find, and the reviews were very good.
This bike was originally almost $2000, and it was on sale for a really great price, so I decided to buy it.
I invested in my health, at that price I would be spending that much for a gym membership/gas for a year.
