My wife just bought me a Garmin street pilot for the trip. After hearing me complain about the crap map program that comes with the 2008 os. I don't really need a moving map, but it could come in handy. 3700 miles has a lot of room for closed roads, especially this time of year. My first gps was a Garmin eTrex, the little yellow one, it was around $200 at the time. I've upgraded to a Legend since then. Pretty bullet proof little gps's. I had a Magellan for about a week, it didn't want to work with my Powerbook for moving maps, so I took it back. That was years ago though.
