have you guys seen those 5ghs asic usb miners that work on usb3 ports.... usb2 gets you 4ghs

i'm thinking of flying over to poland to pick some up. would anyone be interested?

BiFury you mean?

They're much like the 3rd in line of the simple USB miners.

Block erupter was the first simple USB miner, 330mh/s speed
Then came the various USB miners based on a single chip (bluefury, redfury, nanofury), around 2.1GH/s speed
And now they've combined 2 of these chips on a single miner

Basically all of them are the same. Bad $ per GH/s rate but they're simple, small, easy to set up, no external power supplies needed, etc.

So sort of interesting for a starting miner, pretty bad for the more advanced miner.
