There are several factors, of course. Such as condition and desirability, also how badly the seller wants to part with it. Does it need any repairs or "tinkering". Consider, too that once P/W has exhausted the parts that are 800B/C, etc. specific, factory support will cease. $200 to $400. My opinion only.
