I've got a 1084S-D2 for sale, that is unfortunately (for me at least) PAL. It plugs into US wall sockets just fine (does 110 and 220). RGB also gives crisp vibrant colors, as it's region free. However, composite will only display NTSC systems in black and white. Stupid me didn't realize that when I bought it from Germany. Sound is of course stereo.
A PAL to NTSC decoder might solve the problem, and they are on eBay and Amazon. I was going to order a good one but I picked up a Sony PVM-20M2U instead.
Not really sure what I want to sell it for. I know I paid about $170 shipped from Germany. Obviously I'm not asking anywhere near that much. I will stress I'd strongly prefer to sell it locally in person. Key word prefer.
Monitor is in great shape, and has the stand and front cover intact. Very little yellowing on the side. Open to trades as well. Perhaps your NTSC 1084 for mine plus cash? An Amiga? A classic system that I don't have? Try me. Here's just one pic:
