I'd go for it, especially if you already have experience with it. And it's selling on Amazon for $160. I've got a old Garmin Etrex Venture series that I am not very fond of. I really want topo, and color. I was kinda disappointed with it, so I never really used it much. I generally use the basic info page, for elevation, mph, and such.
They have much better, and easier GPS units to use out now.
