I just made an appointment to get my alignment done at Level Auto:

So we'll see how its goes. Their supposed to not have a problem with lowered vehicles & their equipment is supposed to be pretty good/current. Plus looks like they keep a nice clean shop. I was planning on going to Woodbridge Alignment but after a quick google seach I came across more then one person with negative things to say about them (outdated equipment, not that thats always a bad thing, doing alignments on vehicles with broken suspension parts, have to go back 2 or 3 times to get thing right, etc). This place had good reviews from the limited searching I did & looks like base rate is $90 for a 4 wheel alignment.
