Hi,
Yes, I would agree if you can afford a map gps then I would definitely get one of those. However these are quite expensive but you may get a good deal on one of these on Trade Me. I have Garmin GPS 60 (the yellow one) and I find it very good for geocaching as it has a special geocaching mode on it and it is in the middle range of Garmin's GPS. I wouldn't get an eTrex on the principle that it is very difficult and costly to connect to a computer however if you don't wish to connect it to a computer than and eTrex would be fine. I would also buy Garmin as they are very reliable and currently is the only GPS that you can submit coordinates to from the geocaching website if you connect your GPS to a computer.
Hope this helps,

P.S. If you get an eTrex make sure you get the new one with the high sensitivity as they're a lot better than the old ones.
