More expensive IS
usually better, though!
It really depends on what KIND of style you want. I wouldn't go over 60$ for anything. And not over $20 if it's not an updo.
Pretty much:
Left down - 10-20
Simple updo - 15-40
Complex updo - 30-60

Again, it all depends. If you're willing to pay a lot - be sure you're at least getting what you want. If it isn't PERFECT- tell the hairdresser so. A good hairdresser shouldn't be insulted.
