I don’t blame you. I’d like to get an AvP Celtic Predator diorama base to go with my Scar, but not for $70. Even on Toy Anxiety.
Within the last few weeks, I recall seeing a TFA Luke Ahch-To dio base for about $30 on eBay. I saw it when I was looking for an extra DX07 oval Luke Skywalker stand to use with RotJ Luke. I need another one now myself to use with TLJ Luke.
