I think Brett's advice is sound, but if you decide to go the "PP in the US" route, I'd certainly recommend Florida for the consistently good weather, if nothing else. You will be on a limited time schedule, I imagine, so although it would be useful to deal with not-so-great weather during your training, you can't afford too many cancellations.
I've only dealt with two schools in Florida (as a renter, not a student): one of them (at KORL) is gone, but the other, Atlas Aviation at KTPF in Tampa, is alive and well, and pretty impressive. They have a good-sized fleet at decent rates, friendly staff, and all the amenities including an approved simulator (not that you'll need that for the PP)...
http://www.atlasaviationinc.com/A bit farther west is another fine school I've rented from: the Gulf Coast Flight Training Center, at Ocean Springs Airport in Mississippi. The weather can get a bit unsettled in the summertime, but generally it's sunny and good VFR. This outfit has even cheaper planes and fuel and a very nice base of operations. The chief instructor is, coincidentally, a transplanted Brit who speaks English as well as American.
Having worked in nearby Biloxi for 8 weeks I can tell you that it's a good area for an inexpensive extended stay, although there's not much to do except fly and lounge on the beach (like there's anything wrong with that!).
http://www.oceanspringsairport.com/I'd also recommend the Southwest, again for lots of good weather... the only place I know personally is first flight at KSDM in San Diego, CA- not as big an operation as Atlas, but a good inexpensive school with a 172, a 182, a Grumman Tiger, and of course my beloved Champ, in which I did my taildragger transition last summer. While I was there there was a young Brit who had his PP but had come to the US for a while to rack up hours towards his commercial ticket back home. He chose First Flight, and flew all of the aircraft they had on the line, including the Champ. You couldn't really do your entire PP in a plane like that, but it would be an excellent time-builder for much of that time (yes, even solo cross-country work) and instill good habits. It's also very cheap and easy on fuel... 100LL is still relatively cheap here in the US, but it's going up and up. I would consider not just fuel burn but fuel prices at the airports in question before making your decision.
http://www.firstflightcorp.com/The site below is an excellent resource for FBO and flight school information- don't rule out schools that don't have big splashy ads and hard-sell some kind of "PP guaranteed in 30 days!" program or whatever- with a little research you may find a more modest outfit that can still do the job for you without ripping you off to pay for the unnecessary bells and whistles and window dressing.
At any rate, whatever move you make, be sure to thoroughly research first.
http://www.airnav.com/Good luck with whatever you decide... I don't want to confound you even more, but you should know that right now in this country there is a
serious instructor shortage. Does this mean you will have trouble finding training? Not really... it's less a problem for students than it is for schools, especially schools that are trying to expand in order to be more competitive. What it means, though, is that there is bountiful opportunity for a young guy who wants to fly a lot and get paid for it... if you do come "over here" for some training, be sure to inquire about that. If the RAF doesn't work out for you, who knows?
