Not really a task you would want to attempt for many reasons. For any modern 4-wheel alignment, the tools and rack equipment are exotic. $200 at a specialty shop would not be crazy talk. You should get a number from the dealer. If it's scary, check out the euro shop. Hack shops are to be avoided as you found out.
I think mine was $180 out the door at an independent local.
