Mugen,
As you will have read, there are pros and cons to whatever decision you make.
In my case, the most important factor was NOT the cost, but having the weather, an aircraft and an instructor whenever I wanted. That simply isn't available in the UK, and probably elsewhere in europe.
I feel that beinhg able to fly 2 and sometimes 3 times a day was a bonus for me because I didn't need to keep going back and consolodating wehat I had done 2 weeks ago (as it was in the UK) I enjoyed the intense flying with guaranteed weather, and after all, when you are learning, good weather is a must. You will ahve plenty of time to learn about flying in cr&p conditions. Get your licence and then consolodate what you've learned back in your own environment.
Certainly when I came back to the UK, my learning curve went up considerably as far as weather was concerned, but at least I had the confidence to be able to fly the aircraft without any worries.
Good luck with whatever you go with
Kind regards
TSM
