X10 discontinued the Rex-10 Barking Dog alarm units, quite a long while ago. After that, a used one would pop up every so often on eBay, but such had dwindled down to almost never.
Now, all in a sudden, over the past few months, Rex-10 units are suddenly showing up on eBay at a pretty constant rate. Most are new units. Plus, the special motion detector add-on for it, is showing up too.
Did someone discover some old, and long forgotten, X10 warehouse stock pile somewhere?
