100% and I agree that's not cool.
I do think that, if given the choice, one would rather have the EverDrive, which allows you to, relatively easily, update the ROM, vs a repro which would be more complicated to update. My guess is the people buying the repros just don't know about other options.
I don't know enough, but I think there is opportunity to educate folks about the options.
Also, perhaps the message shouldn't be to the buyer, not to buy, but to the seller, not to sell.
