I have a 1-up trainer. Currently I am using my Garmin 305 for winter training. I like the calorie counter, the training programs, the speed, cadence, and HRM. Its excellent. However, I am wondering if there are any other computers that work excellently as training computers? I don't need wireless, and I don't need GPS. Therefore, I expect I should be able to get something much less expensive than a 305!?
