z-your best option is to troll cl for a used Cyclops or Kurt. None of these trainers have odo or speed, but you can mount the sensor for a wireless bike computer on the rear stay and put the magnet on the back wheel.

Second the comments about tedium. You have no idea how tedious indoor trainer work can be. I have a computrainer that I can't stand to use. Get a good fan and put it where you can either read or watch tv. You may think it'll be tolerable b/c you've used a treadmill in the past, but a much shorter treadmill workout is effective. The tedium factor is why spinning and rollers are popular. I wouldn't recommend rollers to a semi-casual cyclist. I like them for the reasons that look171 stated, but they do require a certain mindset.

Oh, I did weld up something for the front of my bike when using the ct, as it was not as stable as I wanted for doing sprint work. And a dedicated trainer bike is nice, if you can have one, as you'll drip sweat like a pig.
