Where can I get a map of Lord of the Rings?

Hope I have posted this subject in the right place?! Sorry if not.
I am about to re-read LOTR yet again and I would like to have a map on which I could mark the travels of all the companions, as I read the book. This is something I have always wanted to do, as I struggle a bit with Middle Earth geography, and doing this might make things clearer in my mind. It'd also be fun I think. But I can't find a suitable map.
Ideally I would like a map of whole of middle earth, or at least whole area covered in LOTR. I would hate to have a really beautifully painted poster map or something and spoil it by drawing on it, so I think I need maybe a black and white map, or pale coloured, and simple but functional. I'd like one that shows all the places mentioned in LOTR, if one exists?
Ideas anyone please? Thanks.
