Been watching the GPS info for a while, and as usual, lots of it from the folks that use them. I'm just in the beginning stages of research for a new "springtime" toy (i.e. maybe an early birthday present ??). Anyway; I'm looking for input from you the users as to cost, functionality, ease of use, which model, etc, etc. Naturally, I'd like the top-of-the-line unit for a basement bargain price. Let the input begin!! Many Thanks!!
