In the today's real world, a keyboard which BOTH includes the speakers and/or larger and more (76 or 88) weighted keys, means lugging around a LOT more weight. Requiring a 'light weight' keyboard (like I do) means learning to accept certain trade offs which means the absence of some or all of the above features. Though both the Tyros & PSR2000 are lightweight (24 & 27 lbs respectively), my personal preference is to give up the built in internal speakers of the PSR2000/2100 in exchange for the much better & more responsive keyboard action on the Tyros. Uncle Dave, I believe you and I have similar desires in a 61 note keyboard. - Scott
