Front end alignment at home

Has anyone bought one of those Summit front end alignment setups? Did it work well? Do i need those plates to turn the tires? I'm tired of paying $100 for someone to do it wrong.

I borrowed a buddies magnetic Longacre Camber/Caster gauge and aluminum toe in gauge. He didn't have the plates, so I bought two 2' x 1' pieces of sheet metal, cut them in half and smeared the smallest dap of synthetic disc brake grease between them. The work great on my garage floor, stay stuck together and are super easy to store. I had to remove the dust cap to fit the Longacre bubble gauge. It's a no brainer.

I'm going to invest in my own tools after seeing how easy the process really is. With 2 Mopars, it is an invaluable set of tools, and the price for everything is just over one alignment out here.

The first time through the alignment process took about an hour. I rechecked everything 3 times. The car tracks straight, doesn't pull and feels planted at speeds up to 130 mph. I do have the Hotchkis adjustable strut rods, which came in handy getting my caster to 5*. It feels very stable.
