I have a magellan meridian color. it works awesome. i also have the topo mapping software. The topo piece of it is terrible, but it has every street and trail i've been on so far. the gps works for me in thick woods and most of the time I have it in my bag, and it still works. It's fun to upload your tracks to the pc and see where you've been. it also has lakes in it too (no depths though).
