I'd expect cheap bike computers or cyclometers to crap out in a year or so. Maybe sooner. If you don't want a GPS, then Cateye is likely a better choice than any other out there. If you want a gps enabled Cyclometer, then Garmin, even their inexpensive Edge 130plus will probably last you 10 or more years. The cost will work out to 2 dollars for each of those 10 years.
