You are onto a good deal, because a 600% in performance means it is a very good one, and 75% off the price means that something is downright wrong with it, but they still sell it because it functions 75% of the time, on full steam and the balance 25% will be deader than a do do :). Or they are introducing a new machine to the market which is also why most prices are downgraded and they are trying to sell of their old stock.  Otherwise the reply above this, is pretty good!. :0

If you mean "$" instead of "%", then the price is $150.00

600%
