Circlet of life everlasting: 25 + 2x7 = 39

one may want to consider a
Artisans/Jeweler's Tiara/Diadem of Life Everlasting
for the higher levels as this would give you 3 sockets to work with. While the level requirements are higher, that is also the point at which you can be expecting to be running into the highest damage dealers unless you were 'rushed' up to the latter parts of the game.

Some may also prefer a Chromatic Circlet of Life Everlasting to get the 21-30% res-all.
