I recommend the brilliant straightforward Cambridge text Collins AV
also the Barbour KJVs use most of CI Scofields headings, with feminine and masculine covers available.
and here is a downloadable PDF of The Cambridge text KJV for tablets and mobiles etc.
When it comes to study bibles I can only recommend
Ruckmans Reference Bible
available in UK at time for truth! and the US at the Bible Baptist Bookstore
and David Hoffmans' Common Man's Reference Bible
