I would not buy any Garmin Etrex, unless it was a new "H" model. In August I purchased an Etrex Venture HC. I can get a quick lock when I am in my basement. My brother-in-law's Magellan, it took forever to get a lock, standing on a street in St. Albert. Sure a few trees, and overcast, but I nearly froze waiting for that thing to lock on. He took it back to Canadian Tire. The new "H" model Garmins work much much faster.
I bought mine at GPS Central.
