Which model of Bowflex dumbbells is best? I can’t make up my mind between the SelectTech 552’s and the 1090’s. Has anyone tried these before? What do you think?

Also if you buy these weights, I think your need to get a bench and a stand as well. Most people who have bought these before on Amazon.com have also bought the Bowflex 3.1 bench and the weight’s stand for easy access during a workout.
