On average how much does it cost to have a nose change done?

It seems to me that I read some where that the average cost is between $2,000 to $3,500.

I have a question... Is it true that years after plastic surgery is done on the face, the skin starts to sag and wrinkle? I am thinking of having a nose change and even a eye lifts and chin change (if possible) but I was told that years later I would regret it... I would hate to spend so much then end up with a saggy, wrinkled, UGLY face!
