MaxMini has a new Cyclops model up for sale that would work great for the Gorgon in a Beastmen army.
This guy is 25 Euros, which is roughly $32 before shipping. It is 75mm to head and the total height is about 95mm. It comes with three different heads that would be great for some conversion work.
I really dig this kit. If I were playing Beastmen I would definitely pick this up.
