As someone else wrote, take a look at the Rich Measures article.

The price of the Palstar isn't too bad for what you get; I think it's around
the price of a new 238B. But you can make one--it's not too difficult to
do, especially if you don't need a lot of power handling capability. I
don't think the MFJ parallel wire feedline tuner is what I consider a
genuine balanced tuner. I took a look at the schematic of it when it came
out and I recall not liking what I saw, but can't recall the details. Don't
hold me to this but I think it involved 2 or 3 caps and a switched tap
inductor in some scheme that might transform the balanced Z to 50 ohms, but
wasn't balanced itself. OTOH, it might work FB for ur power levels. BTW,
MFJ may have come out with better models since then. I would consider the
homebrew route myself.
