I'm considering the purchase of a GPS for my travel bike (a Bike Friday New World Tourist), and would like to hear your suggestions about which models are actually useful (and which should be avoided). I'm primarily concerned with navigation and map display, so the various "enhanced cyclometers" models (such as the Garmin Edge seres) aren't really in the running. The Garmin GPSMAP 76Cx seems promising, although I'm by no means set on this choice... it's a bit more $$$ than I'd like to spend, although not by an unmanageable margin.
Whatever unit (if any) I end up getting, I'll need to mount it on the stem rather than the handlebars. I'd assume that most of the bike mounts can accommodate this, but confirmation for any recommended model would be a plus.
