CrunchDeals: Magellan RoadMate 1412 GPS for $100
The 4.3-inch touchscreen device features NAVTEQ maps, 6 million points of interest, text-to-speech, SmartDetour, 2D and 3D navigation view, and three hour battery life.
So all in all, a pretty straightforward GPS system. Not a ton of bells and whistles here, but the price is definitely decent. Free shipping, too.
