I want to buy a trainer. What is the difference? do I want adjustable resistance? some say it does it automatically.. anyone experience with this?

Any help or insight would be appreciated

In a magnetic trainer, the resistance increases linearly. Twice the speed equals twice the resistance.

In a wind or fluid trainer, and in real bicycling, the resistance increases exponentially. Twice the speed equals four times the resistance. Wind and fluid trainers feel more like real bicycling although the wind trainers tend to be too noisy for my taste.

I personally find adjustable resistance to be of little value. I generally just use the gears on my bicycle to give me enough resistance changes to get an adequate workout.
