This is a so called "Clone". Among Dreambox users this means an illegal copy of the original product. There are many of these out there now. And the build quality is ok. I did buy two DM500 a while back. Not from that website though, but another clone of the DM500 thats looks exactly like the original. But they was only USD60 each.
If you want to compare prices, look at the original boxes from Dream multimedia. The DM800 and DM8000 are far more expensive. I think the DM8000HD is more than EUR1000, and even that only have a 400Mhz CPU.
