When I was reading the Harmony-Central synth BBS most players there would say:
Piano - Weighted keys
Organ - Non weighted
Synth - Non weighted
Many musicians (who can afford it) have a weighted keyboard for piano and non-weighted for synth/organ. If I had the money I wud buy a weighted piano board to go along with my PSR550 (even though I have never played piano) (dream on buddy).

SqueakD,
I have a chorus and another melody line or instrumental break for acoustic. Will try my hand at recording tonight.
