I'm thinking of buying a RD-600, but I hesitate because it's such an old keyboard. I like the number of sounds and the ability to change the EQ on the keyboard (before it reaches a sound board), but I worry that the samples are a past generation of samples. I really wish Roland had the same keyboard out with new samples (the best ones on the RD-600 are a little too close to those on my MicroPiano).

Unless Roalnd is about to release a new version of the RD-600, it seems like there isn't much out there except last year's Yamaha synth (the S-80, which sounds ok, but not great.) And I've thought about getting an RD-100, but it has only one decent sound (the Piano 1 sound), while an RD-600 has many more (older) sounds, and is selling for about $1500 these days (about the same price as the Yamaha S-80, itself a year old.)

All I want is the best piano sound with some variations. I don't want a thousand other sounds that I will never use. Is it best just to get the RD-100 and the Roland JV-1010 module? (Or is it true, as I've once seen it claimed, that the RD-1010 sounds ARE the RD-600 sounds, but without the ability to edit them as easily as the RD-600 allows you?) Or is it better to get a cheaper controller and the JV-1010, if the JV 1010 has sounds that are as good as or better than the RD-1010? (Why is this so complicated?)

Try the Yamaha P-80. It's the best I've seen. The S80 has an edge in the synth section, but the P series really shines in Piano-Land!
