Hello everyone, I am fairly new to bitcoin and bitcoin mining in general. For the last week or so I've been mining litecoin but only at 200kh/s so I am looking for alternatives for bitcoin. I was looking into ASIC's from Butterfly labs but it seems a little fishy to me.
Here is a 5GH/s miner for $280

At these rates legit? And from what I read it would take nearly 3 months to deliver. Will the bitcoin network be so flooded with ASIC's/difficulty go up to the point where this miner will not yield a profit? Also general ASIC thread.
