DIY Alignment?

It seems like it's getting harder to find alignment shops that can/will align a car to anything other than what their computer says it should be. I saw a commercial for DIY car alignment equipment. It looks like it would make aligning your car to your own specs a breeze. Does anyone have experience with this product? Do you think it would work well? Is there a better way?
