Hmmmm.......... So many people ask these type of questions and being as we are all so different in what we expect from life your question is very very hard to answer.
As most people that have visited the Phils a lot will tell you Manila and Cebu are very expensive and the rip offs are rife........... deep, deep in the provinces you could live on a fiver a day but c'mon that is a real spartan existence, it's all about finding what suits you.
You need to get out there and weigh up your own costs, luxury to me maybe depravity to another etc etc, have a long vacation and check it.
Enjoy..............
