Two opposite end of the scale for you.
Me? I have an Oregon 550 with Canada topo. Camera, compass, waterproof (think camera) big touch screen. Does a hell of a lot of stuff, more than I need really . Kinda pricey tho but very cool. Good Garmin support.
My buddy - hardcore GCer. Got a mgellan Explorist GC - loves it to bits but quirks have been reported. Megellan seems to have stepped up to the plate a bit as far a support. Firmware has fixed most of the issues according to my buddy. No camera, no compass, small screen and text but cheap like borsht. Big bang for the bucks if you can live with the config.
Both are good in bright sun. In fact the 550 is better in sun than shade which is backwards for most screens.
Now I've really made the choices really tough for you Me bad. Ü
