It looks nice - but I dont think form should follow function.
Why have only 220v Power supply, is putting a switched 110/220 PS that hard?
BTW - Spazmonkey, I think you need a 'step-up' transformer, not step down. But I could be wrong, I have never used/needed one - but logically you want to step UP 110v to 220v, not step DOWN 220v to 110v.
Why put the Video out right next to the JAMMA connection? I realizie they want you to use this JAMMA extender card, but that seems like a pain in the ass. Keeping the supergun flat and inline with the PCB will require a large flat space. Dont get me started on lack of component video out.
Why put the coin button on the back? Put at LEAST the coin button on the front with the controller. I would put the power switch and the coin button on the front, but thats just me.
And finally, $70 shipping. I dont even want to start on that...
Im just bitching becasue I built a few Superguns and have learned how to do things right.
