Agreed it is over priced. As far as expert knowledge, a lot depends on which store it is at, or who you talk to.
On the plus side, Guitar Center is not 'in love with their stuff', like so many small music stores and private individuals. They want it gone. I have got many great deals from them over the years on a wide variety of gear.
Interestingly enough, in my dealings with them, they have always also been completely honest with me.
