$795 is a lot of money, to me.
But when you look at the prices of current production guns, and compare what you recieve in return for your hard earned money, then a LNIB 645 may be worth $795.
Don't forget, there were not a million of this model made, they will not become more plentiful as time goes by, and the price of a LNIB 645 is unlikely to decrease.
On the other hand, you could buy a shooter grade 645 off the internet auctionboards for around $500 + shipping and transfer fees. How much do you then have in a shooter grade 645? $575? $600?
Hmmm........$795 at the LGS doesn't look so bad......does it?
Buy it, shoot it, love it. You will be glad you did. Regards 18DAI
