How many of you are GPU only miners?  I have 75 GPUS running for 2 years with 4.2 kwh electricity and the GPUS are consistent making money and paid the themselves off 18 months ago.  I'm planning on slowly expanding but I don't see any reason to buy ASICs, the ASICs I've had have been 50/50 profitable.  With GPUs they also have high resale value if you want to close up shop and liquidate everything.
