Query: New to GPS units

I've been watching prices on GPS units for quite a while - waiting until they got below 150. I am very happy with my Garmin Nuvi 200 purchase. I'm not a technical person but it was very easy to start up and operate. The size is perfect to carry in other vehicles and so far the accuracy is impressive. I was happy to see that Amazon noted that the unit had the updated map for clarification - there were some conflicting reviews. I'm very happy with my purchase and would recommend highly.
