I had a turbografx back when the system came out,was awesome but I let my older brother borrow it years later and now it's gone,still have the box but that's about it.
I thought about getting a pc engine as well,just sucks the system by its self is a bit up there in price,also my buddy lives in Japan and I asked him if he ever seen a pc engine in the junk section at Hard Off,his answer was never.
