Thought I'd take a punt on one of these, interesting cable. Have been using one of thefoo.83's SCART cables with a Retro Gaming Cables SCART-BNC adapter until now.

I reckon the picture's better with this new cable. Looks a bit sharper, not much in it but it's a more elegant solution (said the man who's living room is a spaghetti mess of wires). The audio leads could do with being longer to reach an amp, but they're easily enough extended.
