I started Geocaching using a regular car GPS. Since this kind of GPS doens't show coordinates very easily, it was really hard to do. So I got this GPS as a Christmas gift in 2008, and I'm still in love with it! I saw that it's one of the cheapest GPS you can buy from Garmin, but is everything I need! It's good sized (5.5 oz, 2.2 " x 1.2 " x 4.2 "), and is really resistant: I drop it all the time, and get it wet with snow, and never had any problems with it. Also, it have a built-in antenna, and unless I'm in the middle of really thick woods, or in the middle of New York, where a lot of things mess up with the signal, it's very accurate. The screen is colored, 256 colors, and you can control the brightness of it. Is also sun-readable. It comes with a base map which is enough for hiking and geocaching (contains lakes, rivers, cities, interstates, national and state highways, railroads and coastlines). It doens't measure the altitude all the time like the better models, but it gives you the altitude in a waypoint for example. And also, it comes with a specific function for Geocaching, just showing the caches on your way, not all the waypoints. It does have a calendar, sunrise and sunset times, best time for fishing, some simple but really fun games for when you are bored (it doesn't happen often, but you can always use it during bus trips...). And it have a very nice travel computer, that you personalize the fields to use what fits you better (max speed, avg speed, time at destination, estimated travel time, heading, mileage, etc.), wich I use all the time. You can also save your tracks. You can also download a program from Garmin.com called Garmin Road Trip, where you can upload all your tracks and waypoints to your computer, so you can empty the GPS memory whenever you need, and still keep track of all your trips. The program is free. I love this GPS and I wouldn't trade it for nothing!
