I vote for the locust, or find some more cedar. There are some old fences running through the woods up here that are very old and they are made of black locust.
One trick that is cheap and will add another 15 years to which ever posts that you use..... Break down and buy a 5 gal bucket of roofing tar or basement wall waterproofing tar. Dip your post into the bucket before you plant them into the ground. If it is too thick you can usually thin it with diesel. If you take a stiff brush or a margin trowel you can also apply it that way. The bugs won't touch it and the water can't get into the wood to rot your posts.
Just an old carpenters $.02
