An extremely long shot but, what the Hell...

Anyone know anywhere other than eBay (already watching it) where I might be able to get a Creative Labs DDTS-100 or any other similar device that will let me hook up my PC and Xbox 360 to my 7.1 speaker setup and switch between them?

It's just that I have just discovered the joys of Halo 3 and similar on a 1920x1200 monitor but 2-channel stereo sound is a tad disappointing...

Oh well, the DDTS-100 joins that list of discontinued Creative Labs kit that it seems only I and a very small number of techie übergeeks actually want/wanted.
