Well I got some good news... The belts he has listed actually do fit the Super Electric!
They are Bando part number STS3M-597 (199 tooth) and STS3M-174 (58 tooth). They are both 6mm wide and have 3mm spacing between the teeth.
Here is the Bando Catalog:

The STS3M-597 is list price of $7.02... and the 174 is $4.63.
So that is good news for anyone looking for replacement belts!
