^^^The question is all there.
try hitting up ebay... a lot of times dealers will advertise on ebay, so that might give you some idea.
You're not going to find any regular store getting them in unless it's a special order or they've had one traded in. Guitars from the Japanese market very, very rarely find their way to UK shores and it's especially rare to see one in an actual shop. Online is definitely your best bet.
i've seen (online) UK dealers selling the chinese-made ones, I think. Assuming those are the ones he's looking at. Agreed about the Japanese-made ones, though.
