I sell both the Generalmusic Wk2module and the Ketron XD3. They are both very good with the XD3 being the arranger with the better styles and sounds. However, the price for the WK2 is around $600.00 and the XD3 is about double this. The only Gem WK2arranger still around is the oriental version which includes middle eastern styles, sounds and quarter tone tuning possibilities. There are still international styles and all the sounds from the WK2 non oriental model and you can load up to 8 user styles from their large library of styles. The polyphony is 32, not 64 like the Ketron and there are 5 tracks per style, not 8 tracks like the XD3. However, single fingered chord recognition and 4 variations per style are on both. The size of the WK2 is much smaller than the XD3.
