Shilling hardware with affiliate links?
I do agree, though, that the USB adapters are nice. I have a couple of PSX adapters and an SNES adapter. The Japanese console manufacturers seem to do a much better job with input devices than the PC-oriented crowd over here. (Although that could just be personal bias; I did almost all my gaming on consoles and in arcades before the first time I tried plugging something made by Gravis into my MIDI port.)
