Go to Runner's Need, they will do the treadmill thing and tell you what you need, and they have loads of brands to compare.
I tend to vary brands between Asics and New Balance. I usually wear neutral, but when I step the distance up and run with weight on my back I use stability shoes.
Get decent socks as well, really worth the extra. Wrightsocks are good basic ones, but toetoes are amazing (they really do work, but they take ages to get on!)
agree totally.
