I do believe that he has a reputation as being expensive. There is a section on the forum called 'Where to Buy' if you look in there you will probably find some info.
If he's the only one selling it then he can charge what he likes. I guess your main question is 'if I buy it will it turn up' and it seems from the above that it will.
As to whether the price is one you are willing to pay, that's entirely your decision.
