Cooperone,
I have this one and love it. It's about three years old now, used by me and my wife at least 4 times per week and runs like a champ. Since I'm 200lbs plus and according to my wife run like a brick I think this is a solid performer. With that said, it's all relative to the user. I have a friend who runs 1/2 marathons and hates it, he tells me it's to cushioned for his taste.
