I have a portable one I take wtih me when I travel and I couldn't picture traveling without it. Even if I planned out every turn on paper or something an accident construction whatever could cause me to change my route and the GPS handles it all.

Need to pick up a co-worker for dinner? Tap in their address and off you go.

Yes they are that good, they will say bear left in 1 mile, things like that.

I love the Garmin line, many good things to say about them but if you search for GPS here you will hear some good things about some other brands people own.

You can certainly get a portable one with maps for less then the prices you quoted.
