I bought the BAL Lock-Arm bars, simply because I could buy just one set rather than having to purchase the entire three set system.
The Lippert looks almost identical, the SteadyFast looks to be a bit beefier. I didnt need the beefier because I have a light weight trailer (5500#s dry weight) but if you have a much larger rig, beefier would probably be better for you.
