What is this Insectaur's Hive worth?

[Lookie]

Looking to sell my Sectaurs Hyve playset. I know it isn't complete, but I don't know for sure what is missing and what it would be worth. Can some of you Sectaurs fans help me out? See the pics at the link below. I know a screw is missing, but not much else.
