I have had the GPS III+ for well over a year now and it has been an excellent performer at a good value. The mapping capability is a definite plus and the screen is very easy to see. I wouldn't pay the extra money for a color GPS. I bought the Map Source software, which increases the capability quite a bit. Downloading detailed maps and uploading waypoint data and track files is a snap. Besides the rock-solid performance of the unit, the software that runs the unit itself is the best I have ever seen in any product. It is versatile, programmable, intuitive, and extremely easy to use. Menus are lightning fast to navigate and one-handed operation is a snap with its ergonomic design. I've used it on a boat, bicycle, motorcycle, hang glider, and even in an F-16, and it has always performed flawlessly. Customer service is also first-rate. If you don't buy a III+, at least make sure you buy a Garmin.
