I just put a set on this afternoon, replacing stock Continentals @ 23,600 miles. The Contis probably had another couple thousand left, but they were close enough.
I bought 'em (and they were installed by) Weber Auto in Glenview IL (Chicago suburb).
Total cost, including alignment, was $1150.00. Future rotation / check-up is free for the life of the tires.
There's another place around the corner from them (C&M) that quoted 1199.00.
I waiting for rush hour to be over so I can take 'em out for a shakedown cruise before a weekend trip to Michigan.
I'm surprisingly excited, I've been chompin' at the bit since I started reading all the positive feedback on these (255/55/R18 SUV) to get a set.
More later after I get some road time.
Thanks to all that have posted their feedback, it helped!
