I am looking for a couple of Alerton Bactalk global controllers. They can be older as long as they still work. The list would include the LSi, BTI, BTI-100, and even the BCM line, I suppose. I just want something pretty low price, I am thinking a couple of hundred or so. If you would like more, give it a try.
I might have a use for some used Alerton Bactalk local controllers in the future. Let me know what you have of those also.
