Thanks guys for the input. I actually bought that last night (put in a bid and went away not expecting to win) and suddenly panicked that I may have spent too much on it, but it's a figure I've considered buying for a while and the price seems reasonable from what you all say.
I think you did ok there bellendra. Like the other guys have said, 135-140 is about the ballpark for this moc in C7 (which is what that one is.). Condition 8-8.5 and you can expect to pay quite a bit more. £160-180 i'd say.
It's a cool moc to have. 8)
