I finally bought one of those Magal stocks from Blackthorne. A couple of years ago the "inventory" counter on their site said "more than 999 in stock." Now they're showing 22 left.
Panaceabeachbum built one a few years ago, and I found someone else, but other than those two, bupkis.
So, where all all the Magal buiilds? Surely there are more than two!
