Jamma Question

I am looking at getting a Jamma System from:

http://www.ravengames.co.uk/

Has anyone bought from here before? Also I want to play MVS stuff so I need to buy a MVS MOBO.

My other question which I am sure gets asked a ton is can I convert the RGB to S-VIDEO? I only have American TV's and it says on their site that it only has a RGB out.

Thanks Blackride

It looks like You and I are on the same page. I also want a supergun for MVS, but I also want to play Jamma and CPS2 games on it. So far, I haven't had any luck. Man, some one out there has to know something.

OK I do see that old Amiga Monitors use RGB. Is this true?
