I recently bought back the KN2600 (SD) at 650 usd and pleased with the price and the keyboard once again.
I sold all 4 technics when they pulled the plug as I thought the bottom would fall out of their market.
I am still looking to buy bach a kn7000 but will not pay more then 1200 usd for it. So I will wait and continue to play the 11 keyboards I have in the studio which includes the tyros 2 and the roland E 80 which is similiar to the KN 7000. time will tell,
