I have been playing with GPSr's for years now. First in the military, then I purchased a Mag 315 which was the best in my opinion for the longest time. Then I upgraded to a Mag Map 330, which I absolutely love. But if I were new to the game and knew what I know now, and that is there are a lot of things you can do with a GPSr (that was a confusing sentence, eh). I would, provided I had about $500 to spare, go for the gusto and get all the bells and whistles, which would be confusing at first, but would provide many hours of interest and intrigue. At best, you will probably want your GPSr to interface with your PC, this is excellent for downloading coordinates, and just all around fun and interesting with a TOPO program. Not only could you map out your caches, but place your tracks on it, and completely research a new area to hide caches. I would go for a Magellan Meridan Platinum with barometric altimeter, already has a PC cable, then purchase the Topo CD-Rom which allows you to download detailed maps into the GPSr and the kicker is, buy the memory card, not cheap, either an 8, 16, 32, or 64mb for holding map info. Yes it is pricy, and they will make lots of money off of people who don't really know what they are looking for, but that is what I would get if I had the cash. Magellan just happens to be my favorite, someone else that has more experience with a GARMIN or others may know of one with those features too, I'm sure they're out there.
