An early xmas present

I am interested in purchasing a GPS system for my car and wanted to get some feedback from you all. I am thinking a TomTom is the way to go right now. I have read good reviews and the maps seem to be the most accurate and up to date. What are you all using in your car? Find these types of systems to be helpful?

Garman seems to be the best out there. Also, TomTom should be pretty good.

Thanks. I have been seeing some great Best Buy deals on the TT 300 and 700, now I have to decide between the two. Anyone used TomTom products before?

*bump*
I am still looking for a good price on the TT Go 300 or the 700 which use the Teleatlas maps (google earth) does anyone have experience with these? Price?
