I owned and used the 60CSX and I've found the only item I haven't utilized to it's full extent is the altimeter. However, the compass has to be the most used feature on my unit. Waypoints, routes, sight n' go routes, all utilizes the compass.

I unfortunately have left the old compass and maps to a wayside, and aways need a refresher on how to use on. With a GPS I always carry enough batteries to last me 3 days away from camp. I understand that the extra $$ but for me its a great feature to have. Mem cards could always be picked up for $ savings at a local computer store like NCIX.
