Cobra 4000
I just got the Cobra 4000 last week and I Love it. I know a lot of people swear by Garmin, However, the Cobra 4000 works great for me. For starters the screen is over 5 inches! The only Garmin that comes close to that it the one that costs like $1400. I got my Cobra for only $599.
So far I have used it to find restaurants and maybe routes I have not thought of that might be faster to locations I have been to before. If you don't have a GPS unit that will do this, it's way cool. You can be anywhere and find the closest restaurant or gas station. You aren't supposed to find things on it while you are driving, but I spent some time with it and I can find locations really fast.
The other thing that I really like about it is it has a trail maker. So if you go off road, you can tell it to save the trail you are making. When we went to Hollister, I used it track everywhere we went. Also, when you are done, the red trail (as it appears on the screen) stays there. So if you are ever in that location again, you can see the trail that you made (You can even shut off this feature or edit the trails that you have made).
The Cobra 4500 has traffic updates. I would not use this feature so I didn't pay the money to have it. Might be nice for the city though.
