Thanks for the reply. Yes, I was looking at the $400ish one. This will sound crazy, but I already own a Duo-RX and PCE GT Japanese consoles. I am looking to change up my collection which is primarily Japanese consoles over to American. I realize I can mod the RX, but right now it's more of a nostalgia thing - I would rather have the American console.
That being said, I am open to trading both the Duo RX (with original 6-button controller) and the PC Engine GT for an American Duo. I assume that is a reasonable trade since the American console goes for quite a bit more.
If anyone is interested, let me know and I can send pics. I am planning to region mod the Duo, so if that's already done, even better.
