I'd like to buy one, but $15 for shipping to Greece is not an actual "shipping cost", it's just a number they came up with. I hate these people who think they've discovered the marketing trick of the century, selling a product for $0.99 and then asking for $50 to ship it. It's not as if I can't afford it, but I refuse to support such slyness.
My PC still has a parallel port, so I'll stick to my parallel-to-Amiga adapter for now, which allows me to use two Amiga joysticks. Has anyone tried to play a double game on WinUAE or MAME using two Retrozone adapters by the way?
