Don’t know how well this will go over here on SRK but I have the same offer also listed at neo-geo. Basically due to recently coming into contact with a Big Red I no longer need my Supergun and would like to trade it for a CMVS. Has composite and s-video with a Neobitz encoder. Looks amazing through s-video and on my Sony CRT Blazing Star has never looked better. Includes Happ power supply and can even throw in the MV-1C (US Bios) for a CMVS with Unibios and is pretty easy to transport. AES collecting just isn’t worth it anymore so now I’ve totally switched to MVS. Thanks for looking.

Sorry it’s a little dusty, had recently moved at the time.
