I asked my computer tech friend about that unit (printed the page to show him). he said it was a good price but was concerned that because of the gamecube going into the adapter then through the computer then to moniter that there *may* be some lag involved. Maybe there is none, but it is something to consider. Post a review of it if you decide to give it a shot. I bet a bunch of people will do this with their soon to be unneeded Gamecube as they get their new Wii hooked up.
