I know this is technically a Japanese Duo and not an American version (and maybe should be in the PCE sales section), but I noticed a few guys are looking for a way to play CDs and SCDs, and this machine will play the American as well as Japanese CDs/SCDs, so...
I'm putting up my PC Engine Duo for sale. Bought it originally from hit-japan on ebay. Unit works perfect, no sound issues, although it has not been recapped. It is also not region modded, so no American HuCards will work. Very minor scratches on unit (barely noticeable). Every once in awhile, the CD lid will pop open (never while I've been playing a CD) so I always use the lock button. This may be the nature of these units, or the catch is getting a little weak. Other than that, there are no issues with this system. Just pop in your games and play.
System is complete with original A/C adapter, A/V cable, controller, and system. It does not come with the box or instructions. Priced firmly at $120 shipped in the CONUS. I'll post a few photos later in the day
