I won't be shy about it, I've gained a few pounds. It's time I lose it. I've set a goal for myself to do some hardcore biking and drop some pounds. I figured due to the insane weather we've had (so darn cold!) that I'd get a magnetic resistance trainer and use it with my mountain bike in the garage for an hour a day or so.

Thing is, I know nothing about these trainers. I was looking to spend no more than 100 dollars, which limits my options. I want something basic to get a darn good workout in, but I'd like it to last a decent amount of time as well.

While ebaying around, I came across the Minoura 500D trainer. What do you folks think of this? It's in my price range and the very few reviews I read spoke highly of it.

Thoughts?
