Hi. I own a couple of US made Guilds and they are truly amazing. I would never sell mine.
I've tried a couple of the Chinese made ones in music stores and found the sound decent but not outstanding. Great value for the money however. There are others who like them a lot. As we all know, each guitar is unique in its sound which means you might just find a real gem that's made in Asia. Try lot's of them.
BTW, a great place to post this question is at :

There's a wealth of experience with Guilds there and users are generally quite helpful. Do a search of the forums and you'll find posts on this subject.
