^ agreed, the japanese ones are where it's at (as you said, the chinese/korean ones aren't bad, but aren't in the same league, any i've tried, anyway). i have a tokai goldstar (strat copy) and edwards lp copy, and like you, they aren't really aimed at the music i mostly play, so i couldn't really justify splashing out £1500 (or even more) to get a decent gibson- especially when i've tried plenty of gibsons which haven't been as nice as tokais and edwardses i've tried (and here in northern ireland, there aren't any shops with 15 of them so you can pick the best one, it's more of a hobson's choice- the shops often have more than one gibson but it's normally only one of each model).
greco, burny, orville etc. are meant to be good too, but i haven't tried them (maybe philly will turn up soon to help a bit with those).
then there are things like bacchus, navigator, momose etc. which are a similar price to gibsons, they're high-end hand-built guitars. I haven't tried any of those either, unfortunately. :(
EDIT: what's your definition of "affordable"?
