i recently purchase my new keyboard after thorough online research. youtube is good to listen to demos & some owners playing. read online reviews like what we have here. i joined music forum & get some opinions. i also downloaded the manual & read it through. at the same time i did visit the shop & just tried it out without the support of any salesman. well, he did show me where the keyboard is & made sure it got power. & finally i decided to right model for me
