Why use a balanced tuner when a less expensive, easier to operate,
unbalanced tuner, in conjunction with a simple choke-balun, will do
just as well?

Insert the 2-wire choke-balun between the unbalanced tuner and the
balanced transmission line.

My link coupled tuner (Johnson Matchbox) cost me less than 60 USD, I
can tuner faster than a T-type tuner, doesn't need nor use a balun.
(Read one less component and its associated loss). So why would I want
to replace it with something that works almost as good?

I use my 500+ foot horizontal loop on 6 and 2 meters with homebrew
balanced tuners from the '63 ARRL Handbook. On HF a balanced double-L
tuner does the trick. The balanced-L tuner does use a balun but it is
between the rig and the matching device. The only problem with using
the Johnson Matchbox is 30M
