I wonder if you can convince a dirt-cheap GBS8200 with GBS-Control mod, to convert sync-on-green to VGA. I'm not sure what options are available for pure sync extraction, since the GBS-Control also does color conversion, deinterlacing, rescaling frames to more or less lines, simulated scanlines on LCD displays, etc.
