I'm with Frizzle. It would be cool if you came up with a graphic with more or less universal appeal to this community (that mame one in your pic would qualify I'd guess) and have a bunch made so as to reduce the price. Maybe you and Santoro could work out a deal to sell them on his site - perhaps he could give them exposure to a bigger audience, thus increasing the number of units you could sell, thus allowing you to get them made in larger quantities, thus reducing the per-unit price.

Maybe you could even have a design contest for the artwork like Santoro does with his tokens.

My wife just picked up 3 barstools just like that, so it would be cool to get something like this for them, but there's no way I'd spring for 3 of these @ 150 plus shipping.
