I would say look for something in your area, as price goes-I purchased vespa 1200.00 sold, engine 700.00 balance 500.00. Now remember that is a project and I needed to think of the components that I need, electric motor, controller, batteries and black electrical tape. I am in the process of getting a list of materials to make a test bench and some sort of voltage test setup.
I hope this helps.
Btw I still am a Hd sportster/buell nut.
