The namco converters are a mixed bag.. I've seen exactly TWO in real life and both were busted. They're not dependable. The Konami ones are better, but the FrancoB looms are AMAZING! Will this be for a cabinet with a Tri-sync monitor? if your cabinet doesn't have a tri-sync monitor the FrancoB loom isn't for you.
Yeah, I'm aware of the monitor 15/31 thing, not an issue, but it's cool you took the time to ask in case I was clueless. 300wins is probably going to sort me on this.
