I am new at geocaching and have used an old Ifinder Expedition C I bought years ago. It seems to sort of work OK as I am just learning how to use it and about geocaching. I have found a dozen caches so far and it seems quite accurate. But I keep wondering if I would do better with less frustration if I bought something that was simpler and easier to use for paperless geocaching. I haven't figure out how to do that with the Ifinder if it is possible. If I opt for a newer machine what would be the least expensive GPS unit good for paperless geocaching. Some thing used that I could get at a pawn shop, garage sale, or on Craig's list might be ideal? Any suggestions or hints for a newbie?
