A surgeons skill level, the amount of time the surgeon has been performing the procedure and the frequency of a particular procedure has a lot to do with the fee that he/she can command.
It's like anything else you buy... One store has something listed for $30, while another is selling the identical item for $50... Why the diff? The store that is selling the $50 item 'thinks' that 'someone' will buy it at that price... Not a perfect analogy, but I'm sure you get idea...
A few years back, I read a post that one surgeon was charging something like $14,000 (USD)...
It all comes down to doing your homework dude.... Research the PS's, compare prices, go to a few consults and then make an educated decision based on what you have learned....
