I just bought the Garmin GPS 12 after doing loads of research, including reading the reviews posted here, and as I first time buyer I was uncertain, but I'm a believer now! I wondered what motivated people to sit down and write these reviews...it seemed sort of suspicious to me. I fully understand now, and I hope to contribute as a way of saying thanks to the other reviewers. This unit is outstanding, as the other reviews state, and I found it particularly wonderful when combined with some free software called GPSU or GPS utility. You can find it on the net (they are out of England). You can download/upload waypoints and make a map. Combination of these two are a must for the beginner to intermediate GPS user who camps, fishes, bikes, or visits places that they know they'll forget how to return to. Just click "GOTO" and then highlight your waypoint and you can leave your brain at home. I've also found that using 4 energizer "AA" batteries gives MUCH more than 24 hours of use; more like 32 hours. Very, very impressed with this device.
