We currently have a Nuvi. It has taken us to some really *ahem* exotic places in our travels. We're looking at replacing it with a Magellan, the one Office Depot has currently on sale for $99. I don't know if it will behave differently or not, but I am at the point I distrust our Garmin, after it gets us to exit the Interstate, drive through downtown, and get back on the Interstate on the other side of town. This is using the "fastest route" option.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
