I refuse to use a return policy just to try out a keyboard...., sadly many will though and then someone else takes the chance of (unknowingly) getting a board that is a customer (repacked) return.

For me...., because I don't perform anymore and don't have the luxury of dropping several thousand dollars (as freely as some here are able to do)..., when I buy a keyboard I simply DO MY HOMEWORK. I read the manual, listen to every audio demo I can, and watch every video online I can.. I read review after review (ignoring all comments about sound quality as that's so subjective) but pay closer attention to the more important comments such as build quality, OS stability, ect. I even go as far as to contact users of the reviews (if their email is available to ask questions).

YouTube is a VALUABLE overlooked option too. Not only do you get to watch personal vids posted on these keyboards, but you can contact the poster and ask more detailed questions.

Buying sight unseen isn't always a bad thing. However, YOU the buyer MUST DO YOUR HOMEWORK first.
