I bought the GARMIN nuvi 200. It was a meager $169 at Best Buy. It has "turn by turn" but not text to speech, so it will tell you to turn left and highlight the entire route, but it will not read off the street name(it is list on the map though).
So far I rikey. I also like the avatar I picked :) BIG TIRES
