Eek don't remind me! I got it for $2k :unsure A year or so ago I had put this on my list of replicas to do in the not too distant future. Then when it appeared in the auction catalog I thought "Wow, I might be able to get the original for not much more money than a commission would cost..." And it turns out no one else bid on it.
I am a bit jealous to be honest haha This is such a cool prop! I just love all of these obscure props from bttf!! Too many to count!
