I've got a used Paladin ratcheting crimper handle with a new 2067 die. Works great on
my DEC MMJ connectors. So I don't need any of these very similar looking kits that
include dies that are labelled RJ11 DEC, DEC RJ11 MMJ, or similar designations.

$150 plus shipping - one of the end views of the dies looks exactly like my 2067 RJ11
DEC-MMJ die set
eBay has multiple listings of "Eclipse 500-031" kit. One of the dies in the kit
is labelled RJ-11 DEC. The side view of that die looks like my 2067 die, but that
doesn't guarantee it's the same or any good. And these kits seem to also be
available new from lots of places, though I also see signs that some Eclipse crimper sets
and individual handles and dies are discontinued. An eBay search for "ECLIPSE
500-031" finds many new for $183.59 (free shipping) and up.
Searching for "DEC RJ11" on eBay finds a bunch of different looking crimpers,
many of which look like they can handle DEC RJ11 connectors with the offset latch (DEC
MMJ). But most of these look to be of lower quality. Watch out as there are also plenty
of crimpers turned up by that search that definitely won't handle the offset latch of
MMJ connectors.
