I'll always give major kudos to my local HD shop in McHenry, IL. The service manager always says hi to me when I'm in the shop, knows me by name and has always been very helpful when I ask him something, even if it's a dumb question by someone else's standard. All the sales people, the manager, parts dept etc have all been great in regards to customer service.
My dad and brother deal with a HD shop in (lets just say) another part of the upper midwest and while my brother thinks highly of them, my dad won't deal with them at all anymore. And honestly, I've heard more stories like my dad's then my brothers from this place. I wasn't impressed when I went there either.
Just my dos centaros.
