Follow-up from my post, two messages up: I successfully ordered replacement motors from Depanne Robot (who ironically, posted immediately above). The motors currently sell new for $36 each.

I confirmed that the motors work, but I’m currently in search of a replacement motor block control board, so if anyone knows of a reliable source, please share it.
