I got a Navigon that was on sale - one of the cheap ones, and it works fine! (Hint, if you are coming back from at gig at 1:00 am, make sure it isn't set for the 'scenic' route option). The main benefit is that it WILL get you where you are going, but it can take you on some odd byways. Best to have a map with you as well, and an idea of where you are going and the route you are taking. It's very comforting to be leaving someplace unfamiliar late at night and just punch in "Take Me Home" and be guided.
