As Chicago weather is not conducive towards riding year around I'm interested in getting a trainer / roller.

From my research:

1. Rollers take some getting used to, will give real road feel and require correct posture. They are also more expensive.
2. Trainers offers better resistance training, doesn't simulate real riding and can possibly put more wear on your tires (I read this one on a review but don't know if it's true).

I'm leading more towards rollers for ease of storage and my computer is mounted on the front tire.

However I can totally see how I would enjoy a trainer so I can watch some tv while exercising.

Anyone want to share their experiences with either or?
