I'm looking for a pretty good quality keyboard for cheap and maybe a keyboard amp too. Does anyone know of a low cost keyboard that can put out good-sounding Hammond organ/Leslie (its all about the B3!

) sounds, as well as relatively nice piano, ep, strings, and can layer the patches? I'm looking to use it for a band, practice, or small venues. The most important sounds would be the piano and organ, as that's what I use the most. Also, some kind of a rotary speaker simulator would be helpful, but if its part of the patch, that would work too. Thanks!
