Any good tranny shops to build up a 4L60E near Phoenix?

[BuickMike]

My buddy has a '02 Camaro SS and needs to have his trans rebuilt / built up to handle a future heads / cam setup. He mentioned that he didn't find any good recommendations from the LS1 forums regarding tranny shops out this way. I recommended Len Freeman out in LV since he did my tranny and I'm more than happy, but I'm not sure if he deals with those trannys alot. I figure a bunch of you guys have F Bodies as well and am wondering if any of you have some good recommendations?
