Good to hear from you, friend!
I'm on the fence. I'd be more inclined to Drop $60 for BYOAC, or something community built like you used to do. I understand that is an additional fee (and effort) to put down for a new design, but I don't do much with mame.net, so I don't know know if I am that hyped for that exact design. Wouldn't mind a cross community design of some sort. I would easily be down to buy at least some. A batch for $30, I would slap down money no mame ones, no problem.
