While most, if not all, GPS units talk to you, you want one that gives you the street names not just "turn right". I also have a Garmin and am happy with it - I travel a lot for work and am in areas I'm never familiar with so it's also nice to have the feature that shows you what's around like restaurants, shopping, points of interest, etc. I also work part-time and volunteer at a local nature center that is shopping for a GPS now so was looking at the newer ones - you can now get them to show you gas prices. One other feature I would recommend is a larger screen (4.3" as opposed to 3.5"). Even though you agree not to look at the screen when driving, it's impossible in some areas not to and having that larger screen is nice.
