From dining room to Questing Lounge: how to make a customizable table top-game board

A couple of weeks ago, my friends and I created an adventuring party to start playing Dungeons and Dragons 4.0. We all got together one night and played using some miniatures harvested from HeroClix and a tiny map from a Lord of the Rings tactical fighting game.

While the first experience was awesome (we made those skeletons PAY!), we realized we needed more than one map if we ever wanted to adventure anywhere else. None of us has the money to dump into buying thousands of maps or printing them off. We needed a cheap and reusable playing surface.
