Old Map Help, Please!

[jedishampoo]

Does anyone know where I can get/print/download a high-quality old map of Britain, circa 1790 to 1810 or so? I have found a lovely site called Genuki (http://www.genuki.org.uk/big/Britain.html) with lovely maps, but many of htem don't print so well because of resolution (and age).

Thankee-sai!
