It's a little more complex than it might appear at face. A) any product that's produced demands time & space in the manufacturing facility that could otherwise be used for other products, B) the 9000 still uses very costly materials and man-power, so the cost is still high, versus a product that's basically stamped of plastic & pot-metal in China, C) the product actually does have to be re-engineered continuously as parts drop out of production, D) it doesn't really sell anymore.
Like most folks, I'm thrilled to own one and wouldn't give it up, but at the same time I wouldn't buy one today. It just doesn't make a lot of sense to pour $5,000+ into a product that plays a dying media.
