Ive got a War of the Bugs caberet marquee (yeah I know its not Galaga) but its still pretty neat and if that works shoot me a PM, btw its FREE just cover shipping
I went ahead and bit the bullet and ordered one of the cabaret / mini marquees from Two-Bit. Total was $90. We'll see what it looks like when it arrives...
So, in a strange twist, I've finally gotten around to this project and have discovered there are apparently two different types/sizes of Galaga Mini marquees. It turns out the new Two-Bit repro I got way back is completely different than the part that is currently needing replacement on my machine that is slated for restoration.
