The WK2 MIDI Arranger (module) is a very nice unit. It sounds decent, is easy to use, small and handy to cart around.
Don, not to make you feel bad, but I think you gave yours away for $300.00. Take a look:
http://www1.epinions.com/inst-MIDI_Controllers-WK2_Midi_Arranger http://www.donedeal.ie/for-sale/instruments/903694 Now granted the epinions estimate is a bit high at $1000-$1500. But the other link of $550.00 Euro (about $775.00 USD) is more in line with reality.
BTW, I have a pristine WK2MA with internal hard drive and the optional 4 part vocal harmonizer & sampler, and a factory gig bag if anyone is interested. (sorry for the ad).
