Several sold on ebay last 2 years or so but haven't seen any decent ones on there in a while now. King is probably the only company still making a new tester today yet. Stevens is still there but doesn't make those anymore they told me or even do repairs. Graham Lee quit making new ones but I have contact info for a woman that still repairs them yet. I have two Graham Lee model 31 but you probably wouldn't want those they aren't my favorite type to use. Look in your mag manuals under dealer listings seeing who is still going or may have old equipment and tools put away not using anymore and buy them out. That's how I tracked down most of mine.
