I have experince from several points of view. I use gps for travel, military, geocaching, hunting, and just plain fun (exploring). For hunting purposes, a mapping unit with topo maps loaded would be most usefull. I prefer Garmin (Etrex Legend HCx is great for the money) myself but Magellan also makes great units. What are you looking for in one? Budget?

Some features that might interest you.. USB connectivity, map data storage on micro SD cards as opposed to internal memory.. color maps.. topo map availability.. and the obvious, size, battery life, and ease of use.
