I went the more costly route because I wanted the mapping and routing features for use traveling as well as something for hunting.I have the Garmin 60csx and have been very pleased with it.I like being able to do much of the stuff on the computer before I leave home instead of working with the little buttons.
I also like being able to mark tracts and see them on google earth maps.I can send a link to my buddy and we can discuss things while he has it on his computer looking at it instead of try to guess at what I want him top see.
