If I didn't get a pullout, I would try to go to one of the newer tremecs that go behind the newer LS's. I haven't driven one personally but several people say they shift way better. The reason they are so much, is Americans haven't been too much of sports car people in the past. They all want automatics in their cars, so there's not as many T56s floating around as they should be. How much difference is the Mustang version of the T56 than the GM version?
