I've seen lower prices than that . And I've seen higher .
Binding, finishing, scalloping, etc etc , add more $$$
Also depends what kind of action you expect. If you are super picky , get someone who uses a StewMac type "neck-jig" or check out "PLEK" if you suddenly get a wad of extra bucks to spend.
Your location should make the price low, except if there's so few guys doing it, then they can charge more than if they had more competition near them.
The internet sure makes it more competitive
the average where i live is about $250.00
i have the stew/mac neck jig in my shop
it is a definate asset in doing fine quality work
dial indicators let me see everything that the neck is doing
as frets are pressed into place
