Philip's Navigator Britain
Price: £19.99 Main scale/size: 1.5mpi/A3
The Navigator's huge scale meant that not a single track or outlying farmhouse was missed, much less the M6 Toll route, which showed detailed intersections with other motorways. And although it was the most expensive overall, it came in at the joint cheapest per page. It included 50 town plans - less than some - but they were all large enough to be useful, and had a comprehensive index. With more than 380 pages of A3, it was a monster, but for the serious road user, it can't be beaten to our Best Buy award.
