Cycleops fluid trainer ! It was a great purchase. I even brought it along with me on vacation. I have a setup in my basement with a TV during the winter, and I follow the training tapes, which helps make the time go by. Summer, I set it up on my deck or in the garage when I cannot get out. You can probably pick one up if you shop around for $250. I picked mine up last November at my LBS, and they matched an INTERNET price of $245.
