Well, I ended up getting one for Christmas, which was incredible. I have a Garmin III+ and absolutely love it. I also hook it up to my laptop and already have about 30 waypoints, some of which are airports, in it. I also have my two homes (LA/Seattle) and more. This device is absolutely incredible. And its fairly accurate. I was on a DL flight last week that had the moving map display. I set it up so it would track while I worked on my computer. Every so often, I would glance at the speed, and it matched what the moving map display said every time. It's the best Christmas present I have ever received.
