Rawko is a huge warehouse just about a mile from my office. I have been inside it, and there are computers and components in large wire bins, wall-to-wall and floor-to-ceiling. A typical order might be sending 4 pallets of 386's to Kenya, sold by weight and shipped by container. Almost all of it is filthy and ugly.
They know perfectly well exactly what everything is worth, and when they list it on ebay, it is because somebody felt that it was "special" in some way. Since they have not listed a Model F in a couple of years, those are surely going home with employees when they do turn up.
If something listed at $100 has not sold after 2-3 weeks, they might accept an offer of $60-80, but there are no "bargains" at Rawko.
Somebody was talking about a numpad that was selling for $1. When they do that, it is strictly to move junk out the door.
