Sad to here about the Stainless Sttel option. But I want to bring in that the detail plastics are very brittle. So in this case the KrakenD20 should only stand in your shelf. One drop from the desk or someone let it fall and its done.
Maybe you should add this to the description for those who not know much about the materials.
Another thing, are you planning on a more usable version? With shorter tentacles? That would drop the price by reducing the material amount and makes it more usable.
