Yup i've read about them. Thought it was a bit expensive though especially if you want two of them.
If you have a paralell port on your PC you could use a 4 playeradapter for the Amiga as a joystick-adapter for the PC together with
PPJoy. I've tried it with a Tac-2 on Giana Sisters in WinUAE.
USB-interface is nicer but this works aswell and is cheaper.
