I have a "Cateye micro wireless" and haven't had any problems with it. I also find it to be very accurate. I did not however get it on sale but even so I figure $45 wasn't that bad. Prior to purchasing my Cateye computer I though I'd go cheap and grabbed one at walmart for $10 (non wireless). Needless to say it had clearence issues and did'nt fit my bike. Lesson learned... don't skimp on the cyclometer.
