We use a piece of waterproof bathroom panelling.
Scribe it with an exacto knife, using a T-Square to make straight lines.
Takes about 1 hour to do a 6' x 4' area. Total investment is about $9.
Very handy to have, since players can scribe spell durations, current hitpoints, and other information on the board and wipe it off with a quick paper towel.
I don't know how we'd live without it.

Before I got that idea, we used a Chessex mat.
