Quoted from Lermods:that's a nice product, I wasn't aware of it. the only drawback it looks like is you have to hook the same type of games up to it (e.g., bw or stern); or can you mix and match?
Rob, I have the Pinnovator system on all my games, as mandelbloom said you can mix and match as long as the Stern or Williams has the 3.5mm cable going to the jack of the Pinnovators system. They work pretty well.
