I have basically the same profile as you - height, weight, neutral mechanics & few running injuries over the years.
I favor the Asics GT2000 series (now at the 2120 or 2130) and I can reasonably get 700+ miles per pair. I rotate around 3-4 pairs of shoes at any given time. But as a reference point, I also got 500 miles out of a pair of Skylons.
I also like the DS-Trainer and race currently with the Speedstar.
