I'd recommend Naples if they have their JAA CPL Flight Training Course approval now. They were starting the process back in August just after I finished my FAA courses. The CFI (Jatin Guar) had to go to Bristol for an upgrade course / flight test with the CAA in order for NAC to be approved.
The flight training there is good, although I've only done the FAA CPL/IR courses there, but I'd expect it'll be the same high standards for the JAA CPL course.
They have a nice Arrow IV with the Garmin 430 kit... :-)
Best wishes,
