My 'picture' is a link to a page on Rand L's website for a good 1 to 1 balun.
As for a tuner ,if 10 meters is the only band you want to us you can just cut the dipole to correct size and it will be TUNED.
A tuner will come in handy when using other antennas and bands but is not needed for one band/one antenna.
I have a good rule of thumb when looking for an antenna tuner....Look for the letters "LDG" and you will be fine.
LDG makes automatic tuners that are great and cost very little more than most manual tuners you will find (manual tuners ,best for money is MFJ)
