I haven't been to either of those dealers, but I think MCC in Villa Park isn't too far away from the places you're talking about and I just had some work on my bike done there. Here's their website:

They seem like really nice guys and they do sponsor the local Rat Pack so they're into the brand, but I wasn't 100% happy in my dealings with them. The quality of the work was good, but I had to pester the heck out of them to get it done, and their communication with me after I dropped the bike off was non existant. When I picked up the bike they had forgotten to do a couple of smaller things and I'm still waiting for some spacers they were going to fabricate for the passenger pegs on my S3.
I guess we're pretty lucky to have 3 dealers around Chicago (4 if you count Racine), but I've only had experience with MCC and Shoreline motorsports up in Racine.
