http://zoomhash.com/collections/top-sellers/products/gridseed-80-chip-blade-miner-5200khsMy first one arrived last week. It's plugged into a Raspberry Pi (along with some Gridseed 5-chip orbs, a Bitfury rig, and a couple of BFL Jalapeños). With scrypt hash rates being roughly equivalent to SHA-256 hash rates three orders of magnitude higher, and with the profitability of some altcoins being about two orders of magnitude higher than Bitcoin (for instance, Sexcoin is about 91-92x more profitable as I write this), 5.2 MH/s on this rig is probably equivalent to 450 GH/s or so in SHA-256 equipment. Even if you limit yourself to the bigger-name altcoins such as Litecoin or Dogecoin, they're 40-50x more profitable. As for me, I let CoinChoose pick the best coin to mine at the moment and have Cryptsy convert it all to Bitcoin.
