I actually bought a used trainer and used rollers for the price of what it would have cost me to buy one item used. I was not sure which one to get and didn't want to invest a substantial amount on $. For $200, I got cycleops mag trainer with block and a set of nashbar rollers.

I heard rollers are less boring but they take awhile to get used to. My plan is to start with the rollers and if I can't cut it, I will sell the rollers and set up the trainer.
