yeah, I know lots about them.

They were given out at Gencon UK (with the super battle droid) in whatever year that universe came out (2009 or so). From what I can tell, they were only released in the UK and since the game has been discontinued, basically no one is buying or selling them anymore and they (like most promos) have just fallen into oblivion.

A couple years ago, I missed an ebay.uk auction that ended for around 10 pounds. But besides gamehollow and their auction that doesn't sell, I haven't seen anything more recent.

I have no idea of actual value though as its one of those rare items that doesn't really come up for sale, yet at the same time doesn't really have anyone out there actively looking. The other factor is that it isn't a repaint so you can't really tell the difference between it and the regular one (except the base) so it doesn't quite have the cool factor as some of the others like the gotal fringer, etc.

Now that being said, I would have some interest in it as a promo collector, but I have seen gamehollows attempt to get the 150 plus (and they keep lowering the price every couple times they relist), and that is way out of my price range.
