wahunter, You picked a fine model.
There is one thing that I would like to mention; New G.P.S. users are often concerned about pressing the wrong buttons and screwing things up.
Any thing that you do, or "un-do" can eventually be made right again as you learn how to operate it.
About the worst thing that can happen is, you can erase your way-points. but if you just bought it...who cares.
