I only play consoles that are ready to use. Call me Arcade Noob.

No way in the following case...
My first KSNS is on the way, and I have many questions.
There is no room for a cab, so I think the only way to play is with a Supergun. I have a KAICO OSSC 1.8, several screens to use, and a 40" TV with SCART.
I don’t need high-end features. I’ve seen Superguns for around $900 – perfect for enthusiasts, I think. But I prefer a solid, smart solution.
Looking around an ebay, 50 - 150€, someone says me, MVS Superguns are not running with SKNS in any way.
I have no idea.
- Which Supergun should I use with the KSNS (Cyvern)?
- Power supply? (Volts? Ampere? etc.)
- use my AES controller? Or Saturn, etc.
- Anything I might forget?
- Should I build a solution myself? (I’m able to solder, but it depends on the requirements. Consolizing a MVS might be possible to me, for example. Never done, but looks easy to me.)
I would appreciate your help and your tips.
