Agreed, Chris; I would also go with the s*70/*75, or sx at this point.
However, if you're trying to keep the cost down, and you don't mind something that's huge and weighs almost twice as much as the Genos, the DGX670 actually has the same sound chip as the sx600, so quite in line with other modern Yamaha arrangers, and the price is lower than any pro psr. The downside is 47 lbs (vs only 28 for the Genos). But if price is more important than portability...
On the other hand, the Roland FPE50 has almost nothing in common with any Yamaha arrangers, except that it's the Roland version of a DGX. Good piano, great bass (the speakers don't frap out at all), limited styles (only 80 or so, with only 2 variations each) but it's small and easy to transport.
Finally, the Casio PXS3100: a little hard to navigate, lots of sounds & styles, but the speakers don't really do them justice, but insanely light (23 lbs) and can even be battery powered.
