What would make the high price "artificial?" It's real money, and it's what the seller wants for their item. If one person is willing to pay that much, there are probably others who are as well, and the ones who wouldn't pay that much are of no consequence (unless the seller is accepting offers,) and do not affect the "value" of the item. If it doesn't sell, the price was obviously too high.
An SX32pro isn't like a gallon of milk you can just walk into the supermarket and buy at the fair going rate, there are bound to be a bunch of people interested in just one item as yes, they are pretty rare. Chances are if you lowball the guy, he'll just laugh and sell it to someone who wants it more.
