Hey buffet1fan, I did get a very nice score on a set of 5 Back to the Future Kubrick's with Biff today for $15.00 plus shipping on ebay
. Unfortunately I need all five of them. Keep an eye out as there are sets popping up every now and then. Also I noticed you registered for Kubrickworld.com, I'm minifig there in case you haven't figured that out yet.
I'll keep an eye out for an auction with Biff for you.
