Well there is an improvement ..I paid about 200 GBP about 4 years ago for three 1:500000 charts plus the 1:250000 which I didn't really need, plus OS 1:50000 mapping which I had to get to allow printing and other useful functions. Still you can get all of the US charts on a CD for about $20 or so. They have a logic that you have paid the tax you get some benefit whereas we expect to pay tax on our tax etc (whinge over)
