there's a site I'm forgetting that mostly sells vinyls like the pretty expensive Marmits and the more modestly price MMS, but I really can't remember the name for the life of me. I think they are selling the Y-MSF Behemoth with its tusks put in backward.
There's Y-MSF but you have to message the guy and make your order through his social media.
Photon Collectibles makes some pretty bitchin third party figures, but like Y-MSF (not third party just a small operation) you have to contact them on their Instagram or Facebook.
9Modelism is another 3rd party, but he mostly does statues other than his third-party Kong. He took down the Kong though because he wants to complete all the orders so the only thing on his site that's kaiju related is his "Urban dragon" cough... Godzilla 1998... cough statue.
And if you have access to a 3D printer, you can't go wrong with Dopepope's files on sketchfab. I've printed his two MUTOs and his flying Hedorah.
There are probably a few other places, but those are the ones that come to mind.
