A good link coupled tuner is your best choice (a la' the Johnson
Matchbox). The reason is simple. It's a naturally balanced tuner. No
need to force the transmitter's unbalanced output into a balanced
antenna feed line via a balun (balanced to unbalanced) because there
is no direct connection between the transmitter & the feedline. The
coupling between the transmitter & the feedline occurs by way of two
closely spaced inductors (coils), one is the primary or link the other
is the secondary.

You can homebrew a link coupled tuner fairly easily although the
small, 250 watt Johnson Matchbox (available on ebay for about $100)
can handle 1000 watts PEP SSB since the Matchboxes are rated for
continuous duty AM fone.[Formula 1000 watts SSB -50% for no carrier =
500 watts - 50% for one sideband = 250 watts]. I have two.

The only drawback for the Johnson Matchbox is they don't extend down
to 160 meters (if you want to work 160).

If your interested in homebrewing your own link coupled tuner, google:

From the search results you'll be able to figure out how to build one.
I built one [not pretty] that works great. I added a cap to tune the
link.



Good Luck
