If you ever make it to Fort Myers, Boardroom Aquatics has a colony in their display tank. Rich (the owner) will cut frags from the show corals. He's got it pretty low in the tank, so the base is more brown than purple, but it is a GARF Bonsai. The frag I took home is at the top of the tank and is all purple.
Also, I just picked up a huge colony of a Bonsai coral at a local shop. Just keep trying. I have one GARF Bonsai and 3 other Bonsai (no frags yet!).
