Re ESB backglasses: my mate from uni actually helped print these!
Generally speaking the Hankins are not well regarded as good playing machines and this will cap the value somewhat.
This doesn't mean you shouldn't buy one for other reasons, but if you are buying as a collectible then you need to know the above.
The Backglass with Darth Vader and the lighting effect are the best parts of this machine. I think with the Star Wars theme and backbox design, coupled with only 350 made (how many left 200??) will see this game increase in value. FJ may increase also given the popularity of the car...the other hankin pins are not worth much in my opinion..
