Hi, and welcome to the forum. Any chance you could fill out your location in your profile and then we'll know whereabouts in the world you are.
There have been a couple of these controllers sold recently, a PM21 and a PM25. They do show up from time to time so you may get lucky. Have you done a search?
Hope someone sees your post and gets in touch.
Regards
Jem
