Frank,
I would buy ANY keyboard that looked interesting to me. I have previously owned
Roland E50 and E80 and the BK5
Korg Pa1X, PA2Xpro, and the PA600
Yamaha PSR3000, and Tyros 3.
I currently own a Korg MicroArranger which I absolutely love, a Yamaha S950, and my Tyros 4.
I try to keep an open mind and if something comes along that sounds good why not
give it a try. If someone buys and sells any piece of equipment it doesn't mean that gear is not top notch. For me it has to fit into my gig needs and that means styles and sounds have to fit the music I play.
