I'd like to see more of these sites. Speaking to operators, it is VERY difficult at the moment to achieve a return on investment quickly enough to keep up with the new releases.
If Stern used the "JB Hi Fi" business model and made more games in a production run, and sold them cheaper - bit in higher volume - everyone is happy. $7000 for a pro is too steep. I think Stern are "money grabbing" here. Stimulate the pinball economy like they did with AC/DC Pro and get more games into more locations.
Color DMD would look awesome.
