Nowadays the Etherwave Pro theremins seem to be out of production. I don't know how many of them were finally built and sold (I estimate not many more than 200, but I would like to know).
Generally they are not seen at eBay: they were expensive instruments (comparing it to an electric guitar i.e.) and people paying for one of them normally they were pretty sure they were going to keep it.
I am trying to figure out what could be the present prize for a second hand , 3 years old and in good state Etherwave Pro Theremin. Not for selling by the moment, but more for assurance meanings.
Any idea?
