Good Keyboard for Performing?
 

I need to know some good keyboards i could connect to an external synth module. Im looking for something with a high quality weighted keyboard very similar to an actual piano. Ive played real pianos all my life so this is very very important to me. I also want it to have the capability to record and playback multiple loops i create simultaneously, for performance purposes. Other than that i dont need for it to do much more. Ive been looking at the Yamaha KX-8 but im unsure if it has recording and playback capabilities. Does anyone have any suggestions? Im also on a tight budget, so keep that in mind. Preferably something under $700. They can be new, used, whatever. Thanks for your help
