Most of the superguns out there, MAS included, will not be wired so that all 5 jamma buttons are hooked up. Given that they are all pretty much the same quality, I would say just find the cheapest one and go for it. I might be selling my Supergun in the near future since I currently only use it for my vertical shooters. I have customized it with the following. 1) Wired for Atomiswave 5-buttons 2) Neo Geo MVS (Stereo/Mono Switch) 3)CPS2/3 kick harness 4) Internal speaker and CPS2/3 voume control + and - 5)Internal speaker on/off 6)Test and service buttons. It had already included a CPS1 kick harness and s-video and composite rca jacks. The joysticks have also been given 2 extra buttons so that they are now 8-button layout using Happ Competition buttons. I believe my supergun was orginally a MAS before I modified it. I'm not sure how much it cost since mine was a gift. Look to spend ~$300 for a supergun and controllers. Good luck on your search.
