Summer is coming!
If you don't mind coming a lot further South you should seriously consider New Zealand. The lifestyle down here is excellent and the environment is great for flying, especially as it's now spring so the weather will be good for the next 6 months. Living costs are cheap and the cost of renting a C172 is about NZD 220 per hr (EUR 120)
You will have to go through a very brief and cheap process to convert your JAA PPL but it is really no problem.
I recommend Nelson Aviation College in the South Island for the most scenic flying and really friendly and professional people, or if you want to be in Auckland then North Shore Aero Club are also excellent.
