nope.

hold on to your money.
wait for summer and next generations of asic miners (5-7TH/s) and be fast on buying to be in batch 1 for delivery.
keep an eye on kncminer and black arrow.

right now you can forget about whole thing.
there are to many waiting in lines at black arrow, cointerra and black arrow that everything you buy right now it will be shipped to you way to late.
