ea..twobits usually always has them in stock, but I will never order from them again after the "incident of 2007" I had with them...hehe
I have ordered the ones from QuarterArcade and always been happy with them. Never have ordered the ones from Steve at Arcadeshop...didn't even know he had Ms Pac CPO's...heh
Good luck with getting one!! I am sure you will find one. I am surprised no one around here had an extra one for sale?!
