@matiki: you invented the fact that the lens was sold within one day! From my original post you cannot make that statement (the lens could have been listed a week ago, I just saw it today), thus invalidating your counter-point.
No offense, but I guess that bhphotovideo has more experience in selling photo equipment than you
And they probably feel stupid selling a second hand item more than what it used to be new, or maybe it's a simple accountant regulation problem that states so?
At the actual prices, I don't see any good reason for people to buy Pentax. Bodies are good and cheap, but then you get slaughtered on the lenses. And it's the lens that matters right?
