I've been away on vacation, but just saw your post. Here is what I'm using. It doesn't quite have the specs of the power supply 2x6 linked to, but it is decent, and seems to be doing an excellent job for me.

Parts Express PS

It's also a little less expensive (that Ebay guy wanted $20 to ship that Pyramid PS!). And if, like me, you don't really want to solder anything, you'll see a detachable mini plug kit on the same page that makes connecting it a breeze.

Good luck!
