I used to use Cateyes but after losing 4 of them in one year due to broken mounts and having multiple mounts break the retaining tab, I decided that my wallet needed a break.

I currently use Sigma wired computers and couldn't be happier. The mounts are twist lock mounts which are a better design than the Cateyes. The Sigma also has a mount for a second wheel size which is good if you have more than one bike.
