I have the Etrex Legend.
For a basic GPS it is "ok". As far as ease of use, it is less than adequate, I feel. I am by no means an expert on these units, but I have used a few. The Legend still requires you to carry a compass (which is always a good idea anyway). If you intend on going to a certain area you can download a map into it, but it only has a 8mb capacity. So once you are done with that particular map, you must unload it from your unit and re-load your next map.
I got mine as a gift so I can't complain too loud or it's straight to the doghouse, if you know what I mean ;D
If I was to buy my own I would look at spending a couple bucks more and get the Etrex Vista. It has a built in compass and 24MB of storage.
