I looked at the TomTom when recently looking for a SatNav, my first. QVC has a good price today, though as said before you can get free breakdown cover for a year from other retailers. It depends on what you want/need really. This is a basic model. If you want it to announce street names or give warning to change lanes, or stuff like cameras, european maps etc., you would have to look at higher models. I don't think theirs is the traffic edition, so the cable for that might be another £50 - if the machine can do it. Some lower end machines do not have a mode that switches to pedestrian, you need to enquire and make sure. I liked the feature that the volume does up depending on the noise in the car - great idea! If that's what you want or need, go for it! Great deal!
PS I chose the Garmin 265, by the way. But each to their own!
