There is no clear cut answer to this one, your own personal circumstances will dictate what you do.
Consider this though, I am doing my PPL in the UK, started 2 months ago, doing 3 evenings a week, main advantage is I am still working, and with my Summer holidays coming up, will hopefully get through in a reasonable timescale. I suppose I will have paid a lot more.
Now, if your talking about hour building...I am off to the States.
