Well, I use an Oregon 600 but there’s a new “connected” version of that too. They don’t work in quite the same way as the Edge models but can be configured with various Profiles suitable for a range of activities.
A good set of NIMH batteries will last 16 hrs or so in power save mode (blanking the screen) but you can always pop in another couple or run the GPS off an external pack (cable entry is on the bottom so works best if bar mounted although I have a L-shaped USB plug too).
Not right for everyone by any means, but worth considering depending on your usage.
