Thanks for your replies. I actually was able to visit several local shops today that have several different brands that I have been comparing and talk to the owners and I think I am going to go with the Ammco. A local shop just down the street from my local NAPA store purchased two of them about two years ago and he has been extremely happy with them. He says he has an average of four to six cars a day on each one of them and they were holding up great and very stable/secure. Mike.
