"Here's your chance to own a monster keyboard - that originally retailed for $13k - at a tiny fraction of that price! $500 (or best offer).
Anyone seriously interested in this item is probably already well-versed in its history, but you can find out all about it here. This particular K250 works fine and has the A, B, C and D soundblocks installed. Ideally the keys need to be reset/rebalanced, as the action is a little uneven, but all the keys work. There's one missing slider cap, but this doesn't affect performance. The original stand, pedal/ power supply unit and manuals (not pictured) are included. The little Yamaha monitor in the pic is NOT included, but is available seperately if you're interested in it. Due to the size of this item, I will NOT be able to ship it. It's available for pickup at my house near downtown San Diego."
