I've got a cheap arsed garmin, but used a £350 tomtom once (I sell them) and hated it! It was a pain in the arse to use, and took me to the wrong place! My bottom of the range garmin outdid it! There's also the fact we get more tomtoms/navmans/navigons/etc. back than garmins, Garmins tech people are a lot more helpful when it comes to aftersales/faults.
