Whenever wiring electrical things (gauges, whatever) I always solder on
crimp-style quick disconnects as I don't trust the crimp connection.  this
is a bit messy.

I imagine that someone should make a quick disconnect that has some solder
inside the sleeve where you insert the wire, so just insert, touch with
your soldering iron, and you're done.  Does this exist?

the most promising thing I've found is this:

which sounds like what I'm looking for.  But $120 is a lot.  I really only
want a few quick-disconnects in various gauge sizes.

Thanks for any help!
