We have our own alignment rack at our shops, but on a personal level, I go to EMD Auto in Anaheim. They're primarily an Audi/Porsche shop but you're going for an alignment not mechanical work. The owner, Thomas, is a stand up guy who'll answer any questions and concerns you may have. Really great dude that is up front and honest. If you're looking for something a bit more hardcore, I used to go to West End in Gardena when I was tracking my Evo's. They set up my car a few times with corner balancing and the whole shebang. Also highly recommended.
