Predator Diorama

[Model Maker Uk]

I'm thinking of selling my Sideshow Predator Diorama.
It's the masked version. Just asking for a general opinion on what it's worth, I don't want to ask silly money but dont want to under price it either. It is sold out on their website as well, wouldn't that bump the price a bit, but it is small so cant ask too much can I ?
I've got both boxes ( inner and shipping )
Any help would be great thanks.
