I received 2 of the AVALON ASIC Batch 2 orders in July. They cost about 55 BTC (~$1500USD) each in February and now I have mined about 94 BTC ($13000) on each (running at about 83GH/s).
The daily mine total has decreased about 10fold, each making about 0.25BTC per day with the latest diff increase.
The cost per day in electricity is $1.50-2 so with current exchange rates and diff increases they should be 'profitable' until Feb-Mar next year (not even a full year).
