The new L7 Scrypt miners from Bitmain are back in stock after being sold out. On the official website the sold-out banner is no longer there and these miners can be purchased. The price is now back down to $9,500 for each miner.
Shop here: https://www.bitmain.com/ then select Antminer, then L7.
The estimated ROI for the L7 (assuming no appreciation in litecoin or doge price) is a little over a year using this calculator.
The miner currently generates around $22 a day in profit after paying the energy bill assuming a $.07 kWh rate. Of course, the utility cost per kWh and kW depends on your local utility.
