See if you have a Keys Fitness dealer close by. They use heavier gauge steel and have alot of extras for the money. Check them out at www.KeysFitness.com
I'm 95% certain that I'm going to go with the NY Barbell rack above with the Chin Up Bar attachment. I can do regular Chins on one side and Underhand Chins on the other. I spoke to the engineer yesterday and he said the Chin Up Bar had a 350lbs weight capacity. Perfect for Weighted Chins!!!....
