I own a boxed unmodded Famicom Titler that I would consider trading for very rare Gamate games. The S-video output looks amazingly crisp, and I suppose you could mod the console for RGB directly from the RGB encoder if you wished to do so.
The Titler is boxed but does not include the original stylus or users manual.
I also have a slightly used (2 days old) Sony PS4 console up for trade as well.
