you can find really decent instruments in each of the brands lines/you mention. Good Balwdwins are jiggy, and a well maintained one can be a really sweet instrument w a good tech.If you are looking at the new Gibson-China Baldwins (which are not bad, they are just a different animal than the old Americans, so best to not compare them), you are essentially looking at higher end Chinese instruments, which can be a tremendous value. If you consider these, I would personally lookat the top end Hailuns, i was VERY impressed by them.Kawai's are incredible instruments and their QA is tops. I have seen them abused to incredible lengths and they hold up under conditions I believe would have destroyed other pianos i half the time. If you can afford it, find a really babied RX, those w the Millennium action are awesome, it's the slickest, silkiest best action I have ever played (graphite components, etc wow).Never been a big fan of yamaha, though the japan made ones (ie conservatory models) are fine instruments, just not to my tastes. Consider looking at a Kembel grand, it's doctored up Yamaha and the few i played has nice mellow sounds.point is, find one w good bones and then a really solid tech to get it to your liking.
