Another option is concrete piles poured in a sonotube, with a galvanized "saddle" that has a very heavy hunk of rebar welded to a U-shaped piece of plate steel that will hold the 4x4 or 6x6 you sit in it. The heavy rebar portion is set down into the wet concrete and adjusted for elevation. This way there is no wood below ground, and the metal piece is hot-dip galvanized so it will last. A recent product I discovered is fibre reinforcement for concrete, and I think it would be excellent for keeping piles from splitting. I found it at Northland Construction Supplies and it's only $8 a bag, which is enough for a cubic yard.
