Classic British Flight Sim

Does anyone have any old 1:500,000 scale CAA maps they would like to sell me? As long as they are readable, it doesn't matter if they are dog-eared or have been written on.

I've moved my virtual cockpit to a different room and there's no space on the walls for my 1:250,000 set.

I have always found the best way to aquire charts etc is to wander into flying schools, spark up a conversation, explain what you are about and invariably they will gladly offload old maps and out of date charts which are just taking up room in their offices. For our purposes the out of dateness is not such an issue.
