I have a Garmin Oregon 600 which has everything I need. I have a few other GPS receivers, but the Oregon gets a satellite lock and establishes a location from a cold start faster than my other units. It uses the Eneloop batteries I prefer and also has an easier user interface imo.

If you don’t need maps, the Garmin Foretrex 601 is great.

I agree with comments above regarding the Garmin GPSMAP 60CSx, that was my go-to GPS until I got the Oregon.
