I arrived in Phoenix with an ICAO CPL/IR and finished my FAA ATP/IR at AllATPS in a few days. They were or are at Williams Gateway Airport and were absolutley fantastic. They mailed all the manuals and checklists to me in South Africa so I could arrive half briefed. They did the rest!
I would recommmend them to anyone and in fact I was forwarded to them by a chap flying in Afghanistan.
Best of luck!
