www.amazon.com I have used many GPS devices such as Garmin, TomTom, Navigon, etc.. And in the end the TomTom products always seem to be superior. Every time I buy a new GPS, I sit in my driveway and do a few simple tests. The first is how fast is it ready to navigate. I don't think anyone will ever be faster than TomTom. Second, how easy is it for me to find a local store I shop at every week... for example the local Kroger's grocery store that's close to my house.
