The other option, if you don'f fancy China, is Bangkok. I've started getting dental work done there because its so much cheaper than HK and if I could have found a shoulder specialist I would have gone there too. But I was specifically looking for hydro dilatation which I couldn't find - for more general stuff you may be fine.
At the low end of this price range would seem like a good deal:
