There's quite a lot of interesting theory in the thread, but I think for
practical purposes my original answer still covers it, under the premise
we're talking QRP with a short feedline of RG58 (a few yards).
Small autotransformer baluns like the LDG 4:1 I use (I haven't tried the
Elecraft one but I assume it's similar), are just really practical because
they have screw terminals for the LW and the counterpoise. It's pretty easy
to build your own if you really want to, but what happens inside that box
is not likely to have a huge effect on the QSO's you manage. For portable
ops, rearranging the long wire/counterpoise a bit is likely to improve your
signal more than switching from a 4:1 balun to a 9:1, or none at all.
