^ yeah, the problem with the (non-prestige at least) korean guitars is the quality control. I wouldn't be keen on buying one online either.
Matchetts normally have pretty good prices, comparable to internet (well, within £10-£20, and you'd end up paying at least that in postage from most UK sites anyway), i think they had an s470 last day I was in (though ring them to check), so that might be an idea.
