I needed a map pretty quick, so decided to try your suggestion of www.dash4it.co.uk
The result: I ordered the map yesterday, I have it today!!! And it only cost me £5.19!
They also emailed me to send an invoice and let me know it had been dispatched and that I should get it within 1-3 days.
How good is that kind of service!
