We're looking to purchase a GPS device for traveling. After using a Garmin and reading several positive reviews, we decided to go with them. I then looked at the different devices within our price range (under $200) and picked the one with the best features for our needs.
The nüvi 755T has most of the features we wanted and fit within the price range. At Amazon.com it was priced at about $180 with free shipping.

You can look at the details on the Garmin site (Nüvi 755/755T).

Garmin continues to build up its nüvi 7xx series portableGPS navigators with its nüvi 755T, which adds a number of handy routing and communication features to an already impressive list of specs, including a 4.3-inch widescreen display, text-to-speech capabilities, media player, and FM transmitter for transmitting audio--including directions and MP3 music and audiobooks--from the device to your car radio.

Garmin's nüvis pack top of the line features into a slim form factor..
New to the nüvi 7x5 lineup is Garmin's HotFix satellite prediction (which locates your position quickly and precisely), Lane Assist (which provides lane guidance and junction views when possible), automatic time zone transitioning, and 3D Building views as well as Garmin Connect Photos to help you visually ascertain your position. Additionally, the nüvi 755T includes free real-time traffic updates from Navteq (for the life of the device) via the included GTM 20 traffic receiver.
