ELK-930 doorbell detector surplus to requirements?

Does anyone have a doorbell detector fro the ELK-930 trio that is surplus to their requirements, and wouldn't mind parting with it ?


There is a trio package for sale over here ==>

Post on the Classified using the term wanted which might work?
I think I have one Elk 930 around that you can have for $25 plus $15 for shipping for a total of $40 if you want it.
