I almost hate to start this... however, REI is temtping me again to get a GPS unit with the new "Sale" flyer in my mail box, so comments on the value of the unit or even carrying another piece of gear...do I want or need it???

So if either of these is helpful, how much more money do you spend for maps and whatever else you need ???
Thanks
