Don,
I'am not sure yet. Other than my Korg KMA I have bought and sold a PA1X, PA2XPro, and a PA600 because of various reasons. Right now I am looking at simple and easy to carry around.

As for being "cost effective". I learned a long time ago - if they don't want to pay my rate someone else can play the gig. I have dozens I won't play because they are constantly griping about my fees. If someone is dumb enough to play for "dinner" or a fee that hardly covers expenses that is their problem but I darn sure am not going to do it.
