Have you considered Pan Am Academy in Phoenix, Arizona?
The weather in Phoenix is better than ANYWHERE else in the world - the sun shines 330 days per year and you can easily fly sorties to California or Las Vegas or the Grand Canyon or Mexico. Sure, it is a little toasty during the summer, but 9 months out of the year are perfect!!!!! I know that pilots from many countries attend the Pan Am Academy. The training aircraft are mostly new Piper Archers and Seminoles (all with sophisticated Garmin GPS). It must have a website you can check out. The perfect weather alone is worth it - at least you'll get a great tan!!!!!!!!!!!!!!!!!!!!
Cheers
