Yikes, that's bad, Charlie.
I can't tell that I really had any issue w/ them. I'd never been to GC before we moved here. As much as I dug Sam Ash in NY, the store's obviously a bit different here but more importantly, it's simply not as conveniently located - we have a GC a few minutes from here and another at Town Square (which I actually prefer, despite the fact that it's the farthest of all).
I've also bought a few things online from them and never had an issue so far. I've recently found that Musicians Friend was shipping from Oregon, which is closer to me, whereas GC ships from Kansas, so I might give them a try the next time. MF and GC are under the same umbrella anyway, aren't they?
Otherwise, I was very pleasantly surprised the few times I've done business w/ Sweetwater. For serious stuff, they're probably the ones I'd want to try.
