Both. I have CatEye CC-CD300-DWs on both the road bikes, and a CatEye Micro-Wireless on the MTB; I have a Garmin Quest which I've used on all the bikes for just over a year (i.e. all of 2006 season, and from about the fall of 2005).

The Quest is so convenient; I've ridden centuries, metrics, long and short rides, all without reference to a single map whilst on the bike - well, OK, planned routes have to be set up to start with, but how else would you do it? Even without pre-loaded routes, the maps in the Quest are quite adequate for navigation.

I've found the GPS to be such a boon for cycling - it certainly beats stopping at every junction to read a paper map! Of course it would be almost useless if the DoD decided to switch on Selective Availability, or if the maintenance of the constellation of satellites was less than stellar… (so to speak…)
