Reply to The CDJ 900. Worth its price tag?

I currently own a DJM 800 and two CDJ 1000s mk3's and in the next year or two will be looking to upgrade to usb compatible CDJ's. Realistically i want something reasonably priced so have ruled out 2000 or 2000 nxs. 900s and 850s are extremely rare to find second hand and just wondering if anyone would have any idea when 900s and 850s would be marked down? or when pioneer would release are 1900 or something. $1300 australian for 900 is too steep for me.
