Ordered a Garmin nuvi 660 today from Amazon
After making two road trips this week without a GPS, I made my way to alt.satellite.gps and found some very knowledgable people there (thanks, Rich and Uncle Ben!). I also made a road trip to Best Buy, Circuit City and CompUSA. Rich pointed out a great chart at GPSTracklog.com that showed which nuvis have the features I am looking for. I chose the nuvi 660, which happens to be on sale at Amazon.com and ordered it today - I should have it by the end of the week.
