What's the general concensus on these scart switching boxes, do they effect the picture quality at all? I can understand that a cheap device would compromise the picture, but what about more expensive devices, do they have any negative impact on PQ even if it's a lot less than cheaper devices? I have my heart set on either the Trilogy 1 or 2 ( http://www.lektropacks.co.uk/dept.asp?dept_id=112 ) to suport my GameCube, PS2, Xbox, and Pioneer DV550 DVD player all via my TV's one RGB socket. Anyone had any experience with the Trilogy Scart Controls? Any help appreciated, thanks!
