My opinion is that in the market there is no product to get this quality of keyboard and at the same time offer aftertouch. To get Aftertouch is necessary to mount other sensors, which get a final touch softer and less close to a piano. The best explanation is that by offering aftertouch; that determines the mechanism, which is unnecessary when the goal is to emulate a real piano, which never have aftertouch. Usually is a "multipurpose" weighted keyboard. There is no other brand that offers aftertouch in this range of keyboards and less at this price. For example the Roland RD700NX do not have aftertouch.
