Deana expressed interest in the little bike that I'm using at work. Here's a link to it:

Even so, it gives me one less excuse for exercising. I can heat up my lunch and ride it while the food cools. It's a bit jerky and wonky, definitely not a great stationary bike, but I think it's better than nothing and it doesn't seem to hurt my knees, so it's worth the $40.
