Cateye's are VERY good unit's, even the bottom line one's and I REALLY prefer, "WIRE" to wireless, jmho. Now since I had to have 4-unit's to cover all the bikes, we went to The Bell 12 functions, wired unit's from Wal-Mart and they've worked VERY WELL over the last 2 years, even in the COLD and rain and their under $20, if replacement is needed. Now mine don't have cadance tracker or heart monitor, ect. which makes them VERY expensive but either of the one's you have will work!
