If it's only $500 it's probably junk. If your less than 2500 lbs like we are you don't need one and most States are the same weight requirement, with only a few exceptions. Most will destroy your brakes and a good air system w/breakaway is going to be around $1200 with install in Florida. These are the only types of brake systems that work consistently and lock up less than "By Wire" cables. I would never use a inside floor pedal control as I know many who have destroyrd the brakes more than once.
