Is this the DPX 1300? It looks like it.
Its just that my Hitachi PJTX 300 has 1200 Ansi lumens brightness and 10,000-1 contrast ratio.
The DPX 1300 has 800 Ansi and 5000-1.
I couldn't sell mine for £350 on ebay. Quite happy now with the new bulb I got though.
Let me tell you where I am. Best of luck trying to sell.
