Re: Problems with my RG550...help needed...
Well, not that I want to play devil's advocate here, but I looked this up, and you don't mention THAT crack in the listing (#270067782181). There's mention of a "hairline cracks by the neck joint", neither of which this appears to be - that is that isn't a hairline crack and it's not at the neck joint (to me that implies the joint where the neck meets the body, which is notorious for cracks, as many of us know). I've had probably over a dozen necks like this repaired, and I have to say that's among the worst cracks I've seen without it completely separating into 2 pieces. When repaired properly, these will rarely break in the same place like this one has, too.
But, all that being said, I'd give you $200 for it in a heartbeat, I have no problem playing a repaired neck, or repairing it.
Also, FYI, your buyer is a dude not a "she", he's a regular here on the forum, too. And I've done deals with him in the past through evilbay and through another forum member, and he's pretty honest, at least always has been with me and he other guy.
Either way, I hope you guys come to a good resolution for the whole thing.
