Trainers???

OK, so I'm thinking I'd like to buy a trainer. I get cranky and whiney in the cold :cryin:, so I doubt I'll be doing more than a couple of rides a month during the winter..

So...I'm thinking of buying a trainer to help get me in and keep me in "bike shape" for the winter.

So many options out there, magnetic, fluid, rim driven, etc.

Who uses one, and what do you recommend???

Thanks!!
