No, they're worth much more than that, if you wrap them up in plastic, and advertise them as rare, new, and sealed.
I wonder how much profit these mass MSX gear sellers make on what they imported from Asia. What is it that their buyers pay for, their service of going through all the trouble finding a good deal in Japan? /sarcasm

Could not that be reported to ebay?Advertizing a piece that you tell your sellers it is new,but in the end it is a used product with a fake sticker on the side?I have a philips audio module that was with the vg8235 i bought,a cartridge that could do 2 seconds of sampling,in very good condition on the original box,with no scratches at all,along with the cartridge that is in top condition plus 1 tape that has demo of the sounds and of course all the manuals of it.Should i just stick a plastic case,seal it and then request 600 euros for it and advertise it "SEALED MSX 8235 AUDIO MODULE CARTRIDGE UNOPENED" ????

I think everyone with a level of intelligence a little above conan the barbarian can easily understand the trick and avoid such lamers.
