GPS Navigation... What to buy?

The roadmate 300 is garbage. Give it two months and it will lock up on you. Then you have to go through the lovely tech support from india that will need you to fax a copy of your receipt to them before they will take it and repair. My suggestion is get a tomtom One. I had one before I got the Tomtom 910 and it was great, just wanted the BT and harddrive for movies.
