Looking for working Mitsubishi CR-E116 Controller

After months of troubleshooting, countless part replacements, and multiple dead ends, I've come to accept that the controller I have is a paperweight. I'm looking for working surplus to get an RV-E2 functional for a youth science program that a local library runs. So far, I've only been able to source controllers overseas with rather inflated price tags considering the quality of the controller itself. After almost being scammed for another junk controller from an automation reseller in China, I would prefer staying as close to home as possible. Any help would be greatly appreciated.

Alternatively, a working E31CPU board for the CR-E116 controller would be preferred considering shipping.
