I read Keyboard magazine's review on the new Casio PX3 and am wondering if anyone has had any experience with it. How similar is it to the PX-330 which has speakers. I'd be interested in the USB/SD card options for playing midi files. I played a PX-100 at a funeral home today and was pleasantly surprised at the keyfeel and piano sound. How much better are the PX3/PX330? http://www.keyboardmag.com/article/casio-privia-px-330/October-2009/101537 http://www.keyboardmag.com/article/casio-privia-px-3/October-2010/121671
