Well my GS2 cost £459 and plays fine. It was a custom order and I waitied about 9 weeks for it via Sounds Great.
The finish is good, but not perfect, and I find it pretty good to play.
I can tell you the Gibsons at a similar price are far rougher.....(Junior, faded etc)
And the far eastern competition is not even close.
But certainly if you plan to buy a shop model try a few out, you can't build a solid mahogany body 2 pickup guitar by hand for under £500 and expect them all to be gems, but the secret is that some of them are. In fact to the stock in sounds Great a few years ago, I remember trying about 20 guitars one day and the one with the most resonance and vibe was a Gordon Smith.
I think the worst one was also a Gordon Smith....
