I've got one, just waiting for a replacement diver pin as I completely screwed the one I have up by using wire that was too thick for it! The carto that is included is junk.
Oh dear - they recommend NR-R-NR wire for the Diver. And the pin holds one end of the wire against the inside of a tiny, fragile-looking ceramic cup, so it's a bit nerve-wracking (and fiddly).
Done a bit more looking online since my last comment; they did indeed clone the BB of a few months ago, it's shiny rather than anodised, and uses a clear-faced
tank (nice to see inside but beware of tank-cracking juices).
Not sure what advantage being able to put an atty on top brings, though, makes the set-up fragile and an MVP can do that job better and cheaper (IMHO, FWIW).
