Just got myself a Tomtom 520 from Pentagon GPS for £260.96 including delivery which I reckon is a pretty good price. Service from Pentagon was excellent. Ordered on the phone late afternoon and it arrived at my door the next day at 8:30 in the morning. Also ordered a Brodit mount for the 520 rather than fit it to the windscreen. Ordered it from DSL Developments, delivery very good but unfortunately instructions not included. Quick phone call and they were very helpful and clearly explained what I needed to do. Always nice to have good customer service after you have brought the goods.
