I don't think the BK-5 sounds as good as instruments five times it's price...it does sound better than it's asking price.

Comparing it to a Tyros4 or PA3X is a bit much...it is what it is...a cheap keyboard alternative to a BK-7M module...nothing more.

It isn't hard to predict who'll be buying one...no harder than it was to predict who'd be selling KMA's.
