It's funny though, like a lot of things in this hobby hype seems to drive prices of these more than rarity. You say there are 5 or 6 known examples of each of those, which are the rarest ones, and they sell for the equivalent of nearly $10,000 each. I bet there are Palitoy/foreign MOCs with only one or two known examples that sell for a fraction of that price. I used to have a Kenner MOC Luke Bespin that was the only known example (submitted it to the Kellerman matrix) and that only cost me £150.
I didn't realise there was 16 of them though which is cool, I thought there were only about 5

is there a page with info/photos on all 16 anywhere?
