I have the lifetime alignment deal at Firestone. Its okay but best bang for your buck. I get an alignment for my car about every 8 weeks because Houston has a **** load of potholes. I would recommend waiting for the alignment special to sign up with them.
Every 8 weeks? Are you blasting through them at 100mph? There is no need for that. My wifes 2008 Toyota Yaris has had the same alignment from factory and it is still 100% true after 140k miles, while driving horrible Houston and back country roads. If you're needing an alignment that frequently, then you have other suspension issues going on. Firestone isn't bad however. Their prices aren't too bad, and from what I've seen they laser align all four corners. And their "warranty" should be redeemable at all their nationwide locations. I would try and stick with a nationally known company, since most "mom and pop" places usually have old equipment, and not necessarily the most well trained employees. A dealership should also be able to take care of it, but they'll probably price gouge the hell out of you.
Getting an alignment every eight weeks is one of the most ridiculous things I've ever heard. But whatever floats your boat.
