Don't knock US training.
IME, UK training can be pretty crap. I could tell some atrocious stories.
My US training was very thorough.
The rumour (which I cannot personally confirm) is that, currently, the half a dozen or so JAA-PPL-capable schools in Florida are packed with students from the Indian subcontinent and, incidentally in the same way as with UK universities, these people pay and expect to get the papers, no matter how, so the "business incentive" is pretty obvious (same as in UK universities, actually, where standards have plummeted to rock bottom).
That leaves just the one in California, which may be OK.
