[Closed] Garmin eTrex 20 (30?)

Anyone got one of these? How do they shape up and what's the bike mount like?

Wondering how they compare to the 800 for bike use. I've been using a 650 but liking the look of the eTrex's:

[b]Physical buttons[/b] - strike me as a better idea in a world of full finger gloves (rather than the 800's touch screen)

[b]Screen size[/b] (probably about the same as the 800? but higher res than 650)

[b]Navigation[/b] presumably much better than the Edge which lacks 'trackback' amongst other things

[b]Batteries[/b] AA's. meh. Edge rechargeable lasts well enough.
