First off - lovely maps in the November Dungeon. It really is great to see Wizards commissioning more new map art rather than re-using their dungeon tiles.

For the laminated maps - I know Chris West does large print runs to get the price down. He's used Kickstarter in the past to make sure that he has enough money pledged to offset the cost of doing a large print run. His advantage is that he has a big following amongst the Star Wars miniatures community so he can secure money up front for a new map. Kickstarter would be a good way to test out the model of a decent sized 11 by 17 laminated map as it's risk free both for the seller and the people pledging money.
