Wow, £7 for the Snowtrooper is an awesome price
There's always been readily available Luke Bespins. I bought a few recently but none were mint cards despite being described as so. I get sick of people not being accurate with their description so i'm resigned to picking one up when I see one in the flesh.
Yeah Luke Bespin and the Admiral were the two most common in the UK. Hasbro UK mixed these ones in with the older trilogo cards as I remember. Red card trilogo Luke was still being manufactured as late as 97/98 (I'm sure I have a list of date stamps that suggest so). I remember a case being put on the shelf of Stationary Box (remember that old store) with older red/green trilogos plus these 2 characters on Long Picture cards. I initially was only collecting the Euro cards but I relented (like most people) and started picking up the other POTF2 on US cards that weren't ever released on Euro card. Hasbro UK and wholesalers by this time started just shipping out US/Japan cards with a small CE sticker on the back and that was pretty much it for POTF2 (although the Flashback cards got a euro card release). I only ever saw the Admiral and Luke Bespin at retail, perhaps the others did too. I only knew the others existed due to the other figures appearing on the back of the card backs!
This was in 1998 and were released the final year that the Freeze Frame offer was running in the US. The year after they dropped the FF and went for a flashback file card and then a plain Green card (a la Motti, Wuher etc).
Rebelscum have a Euro POTF2 section here:-http://www.rebelscum.com/eurolist.asp
This lists many of the variations etc. The GIGI ones used to be sold in wholesalers for 2 pounds at one point. I remember buying a load of the GIGI SOTE and D-3BO (Threepio)! Sadly all gone when I sold off my modern stuff years ago.
