Blades and Cubes or Pre Order ???? 1st post :)

Sup bitcoin Forum Members !!! This is my first post and I'm pretty much a newbie miner. It took me like a week to set up one blade lol. I was lucky and got my erupter blade cards at pretty much the all time low of 187$ per card for the first 8 and then got 8 more like 2 weeks later for 267$ per card I think it was. 160gh at 1328 watts power runnin on slush ....

Now I can't decide if I want to get a few 30 gh cubes that run 200 watts each that can be at my door step in less then a week, or try to get on one of these batch 2-4 pre-orders from the 3 or 4 possible legit websites!! With what happened to Butterfly labs shipping dates will most likely happen again with everyone's per-order. I guess if you had the 13k to buy the big daddy from knc you might actually get what you ordered within a couple weeks of there delivery date. I really want to get in on a pre-order in the 400gh - 1 th/s rigs (cointerra/hashfast/bitmine/butterflylabs/blackarrow etc) OR should I just push to 300-350 ghz with ASICminer and just fork over the power bill money till I can afford a couple knc miners off eBay or whatever ASICminer is not talking about. (V4 Cards???) Any suggestions or feed back appreciated ..... Thx.
