I am recently checking on the GPS and I have never bought one before, so while I checking out the websites, I found this Garmin GPS Comparison Chart from www.garmin-250.com.
Basically it shows all the models from Garmin with current Amazon prices , so it is very convenient for me to compare. I prefer the models that has Speech to Text feature. Text to Speech feature is a important since it would be difficult to know exactly where I am during driving a car. But I wonder how good their speech quality is. Maybe I should check out Youtube .
I am not sure if I buy Garmin brand, but it is the most popular ones. I wonder how those other non popular brand GPS (Sony or Navigon) are in terms of quality over prices.
Latest Models (Nov 2009)
Amazon prices reflect Early November 2009 prices and maybe different at the time of your reading.

Eventually I bought Garmin nuvi 1200 but Garmin nuvi 1250 is a better deal with speed limit display function but they are almost the same price. Bluetooth capability is useful if you want to connect your wireless phone and use GPS as hands free device.
