Controllers

I have 2 smart rise controllers - master and slave. both were used on a job a few years back and were in use for approx 1 year.... customer had some legal issues, requested we remove them - yes seriously and yes ridiculous.... anyways we have no use for them so throwing out some feelers to see if there's any interest.

I'd have an interest... What would you want for them and where are you in the world?

Thanks!
