Roland will, more then likely, have a better buld quality, a better keybed, and will also have full sized keys. The E50/60 will not have organ flutes like the G70(the PSR1500 does have organ flutes). Not sure what "box" features are. Roland will also make a 76 note keybed (E60). Yamaha will probably not.
