Does anyone actually have one? Do they really get 832 MH/s?  How come all the other dual-chip FPGA's only get around 400 MH/s?

See here and many others. https://bitcointalk.org/index.php?topic=60586.0

I read the tread and ordered one about 1 hour after reading the tread. By the members it really does the MH/s. The only "problem" seems to be, that the company which produces it is new and quite unknown. You have to trust them. If $600 is an amount you would care too much about, then I would recommend to wait until you can be sure to really get one. On the other hand, some guys ordered a handful of them on their own risk and got their singles. So so it´s on you. If you live in EU, then you can add $88 for shipping, another 19% of vat, also add some 5% of taxes, and finally add some coins for the paypal exchange rate. Thats all together nearly $900.

Interesting.  Why is it's hash rate so much higher than all the other FPGA miners out there like Icarus?

So far we don´t know what exact kind of processor there is inside. But it draws 80 watts at work, I guess that the other FPGA-units draw significantly less. Even less in W/MHash. Just put together some more FPGAs and you will have same Hash-Rate at less wattage. But you also will have a higher price to pay, which makes the other solutions less interesting. Thats my understanding of it, for more data just search the treads.
