New Miner shipping: Hashbuster Nano

New mining hardware is always good news. Two weeks ago there was a forum post announcing a "Hashbuster Nano" ASIC miner based on the Bitfury chips we already have seen on Miners carrying the "Block Erupter" brand. The announced chip is now actually shipping and you can get it from the Bitcointalk forum post linked to above as well as from eBay, where I spotted at least two auctions as of now.
Essentially what you get is the power of 7.5 Block Erupter Sticks (branded "Emerald" or "Sapphire") at the power consumption of about two to the price of about six.
It is definately an improvement over the sticks with the better efficiency, so here are the two in comparison:

	Block Erupter Emerald/Sapphire	Hashbuster Nano
Price	25$ (trending down)	140$
Hashrate	333 Mh/s	2.5 Gh/s
Power consumption	2.5 Watts	4 Watts
Power efficiency	130 Mh/s/Watt	620 Mh/s/Watt
Breakeven Timeframe (as of this thread)	200 Days	140 Days
