I currently have the cateye micro wireless computer and am looking for a cheap alternative that has a rear wheel speed sensor and cadence sensor so that I can monitor my progress while on the trainer. I've looked around and the cateye computer with the speed and cadence sensor is like $100+ and the garmins look awesome, but I don't think I can justify the costs. I bought my cateye micro for $30 so hopefully you guys can suggest something that you guys use and knows works well and isn't priced too high!
