Good luck, they are hard to find I think.  I have two NTSC versions as I am in the USA, but only one of the "break-out" boxes that has the S-Video (can't remember the actual name of that box component at the moment).  I really liked the GVP IV24 when I first got it and only had an A2000 with no other flicker fixer/scan doubler at the time.  Too bad GVP did not survive longer, I liked their products professional look and functionality (still have an A530 on one of my A500's).
