I've used various different brands, and they all work well. You can't go wrong with Cateye.
I have three of those Mach 3 computers. I think I got two at Nashbar. They are very reliable and easy to use.
Since I own too many bikes, I ended up getting a Garmin Edge 200 which uses GPS rather than sensors on the bike. This way, I don't have to maintain computers on all the bikes or laboriously tally up my miles.
