Sorry, I said relatively common, but then rare - I meant "relatively" in comparison to just a few decades later, when they become totally extinct. You have one or two units entirely of made up of LAMS in 3025, IIRC, and a factory making spare parts. Every House has some, as well as some mercs. They're prized, but hardly unknown. They're clearly precious lostech, but compared to the 3060s, it's not so bad.
