I'm seriously thinking about getting an etrex 20x, but need to get my head around the maps situation (never used a GPS before).
I gather there are cheap/free map options so I'm interested to hear what works well.
I plan to use the GPS for UK mountain hiking (Lake District, Snowdonia, Cairngorms etc). I expect I'll primarily stick with a map and compass, using the GPS more when visibility is poor or when I want to double check my location etc.
I always use 1:25k OS paper maps. Do you need 1:25k on a GPS, or can you get away with 1:50k if complementing a paper map?
