I have both the XD3 and the SD3 Ketron modules in my store and available for sale at really good prices. The XD3 is available for $895.00. It originally sold for $1595.00 a few years ago. I also have a one year old SD3 which is the same as the SD5 keyboard. This unit is in brand new condition, not a mark on it. It sold new for $2495.00 and I'm selling it for $1495.00. I have the original box for the SD3 but not for the XD3. Both modules feature all the great Ketron sounds, styles, mic input, keyboard and accordion modes. The only module ketron is making now is the Audya4 which is much more expensive then these two.
