Hi Itsky;
As a general suggestion I would recommend a vehicle mounted large screen GPS if you are doing a lot of highway driving. They are much easier to read and probably safer to use than the cradle mounted handhelds.
Your intended useage however seem to be ....
What I really want to do is upload 4x4 trails that friends have completed and be able to follow their tracks. I then want to upload my tracks to a nice topo map.
So my question would be, what GPS's are your friends using? To transfer tracks, waypoints and routes requires some degree of compatability. With the newer Garmin and Lowrance (I'm not familiar with Delorme so can't comment) units you can simply save your data to memory cards and swap the cards with your buddies. To transfer data any other way requires additional software.
So find out what your buddies are using, go with the same brand and pick a model that suits your preferences and budget.
