Can anybody recommend a very knowledgeable Giant dealer for service in the Phoenix metro area, preferrably one that specializes in mountain bikes? I have an '03 NRS Air that still is exhibiting some play in the rear shock mount (probably a bushing issue) and I have not had much luck in working with 2 dealers. Even though scores of people on MTBR have reported the same issues I have, these dealers shake their head like I am the first. "We've never seen that before" they say. And that's when they go hunting around trying to figure out the problem.

I know I am not the first to have this problem around here and I'd like to find a dealer that knows their sh%t (if you know what I mean).
