Tom Tom one here
I asked this same question a while back and after lots of research, we finally settled on a Tom Tom. Since the kids decided they liked the English female voice though, we call it Tam Tam...We love it and my husband takes it everywhere he goes. It does get a bit weird though when you start talking back to it .. We picked it up on a special sale at Best Buy for $199.00..I have never seen it that cleap anywhere again...
