I am elderly and am finding it increasingly difficult transporting a Tyros3 to functions. To this end,am considering a Korg PA800 which has the speakers built in. What a I need to know(not having set eyes on a Korg PA800 let alone heard a demo of my era of music) how do the two compare. As I have mentioned, I am elderly,and accordingly my music is of the pre 1960 era. Your guidance would be appreciated. Regards Jim
