I've been going to this store for a while now, and have always had a good experience. The staff have always been helpful and willing to take their time to help.
I was in last Monday with a problem with my mod (it was out of warranty btw) and they started working on it to see if they could get it working. Found out there was a problem with the wire. They did this just to help, didn't charge me, only asked that I continue to shop there. That's what great customer service is all about.
