Korg X5D, Alesis QS6.2, Roland Juno-D, Roland RS-70, or Yamaha S03?

I need a synth that's light weight, has a lot of organ sounds, assignable/control jack for volume pedal, and where I can "turn off" the touch sensitive or touch response from the keyboard/manual.

Your input on this matter will be greatly appreciated. Thanks in advance for your help.
