I'm just wondering if anyone uses something other than vinal mats for gaming. I would really love to find a white board or clear plasic board or mat, just something with a one inch grid. I've seen white boards with grids on office supply websites, but they're all several hundred dollars, so I'm thinking the clear plastic might be the way to go. That could even be overlayed on maps and stuff. Does anyone have any other ideas, or sites where I could buy something like this?
