Any place that will set the rear toe and camber to your specs is good in my books, or atleast if they tell you that they tried to adjust them and they are seized.

Most shops will charge you for a 4 wheel alignment, when all they do is straighten the steering wheel and adjust the front tie rod ends. Once your front wheels are straight you may not even realize that they didn't even adjust the rears. Best is to ask about the rears, especially on a DSM.
