recommendation of GPS Systems

I bought the TomTom from Buy.com about 3 months ago and like it a lot. I have used it to drive from Baltimore to Toronto/Erie pa. and the Charlotte game last week and several other places. It's pretty easy to use and comes with a US and Canadian map. You would have to pay for any other maps, I would suppose.
If I were to get a new one I would seriously look for one that has text to speech (speaks the actual name of the street) but with this one it reminds you so many times before any turn you have to make and you can see it on the screen. It sticks on the windshield and is easy to pack away in a bag also.
I also found a site to download extra voices if your into that kind of thing. By far the Homer Simpson was the worst impression I have ever heard but it's almost so horrible that it's funny. Then there's Ozzy throwing the F bomb in with his directions.
The thing will make you want to get in your car and drive across country. 1 month till our road trip back to Nola..............
