whilst I don't know much about SFTC, they might run out of aircraft soon slight problem with their Liberties
Jesse over at Clamback & hennessy is very good & know's his stuff, they also have some of the best maintained a/c on the field & all IFR yet still the cheapest to. having said that flight tests over their can be very stress full..........
Sydney Aviaiton center seem quite good as well, although at camden Airborne Aviation are a good bunch flying all near new aircraft (2000-06 models)
but at the end of the day go visit them all speak to their instructors & see what feels right for you.
Make sure you ask about ground breifings!! eg do they have set briefings they deliver to students before the start of a new exercise etc.
a good breif on the ground will save you time & money in the air
