A couple of years ago the "going rate" jumped from $50-80 to $100-120 very quickly.
Good ones have sold since then for well under $100, but not consistently.
I would guess that today's rate is in the "low-mid-$100s" for an average one and the "mid-high-$100s" for a nice one.
My guess is that he will get the $250 after a while, because somebody will build up enough desire.
