Change the third line, it's more stable and it'll prolong the life of the sticks unless you're cooling them. If you're running the PI on that hub try unplugging one of the miners.

If BTC/USD goes to 10K this year you'd make $200 on the year per stick. Otherwise you're not likely to make a profit.
Wise words. No one should be buying an Antminer thinking they're going to make a "profit" on it. Even if you get one fairly cheap for them ~$60: you're not going to be able to mine BTC, PPC, or anything else and get any sort of ROI (with electricity costs), absent BTC/PPC/ALT appreciating enormously.
I sure would like to know how you come to this conclusion. First, for me electricity is not an issue, I live in an extended stay hotel, and they pay the bill. :-)
I have 7 Antminers ($65 each cost, $455 total) overclocked, and running at an average of 1.95 Gh/s for a total of about 13.6 Gh/s. All other equipment (USB hubs) I had already.
On the Eligius pool I am mining about 0.01048576 BTC in LESS THAN 3 days. Their stats are down, so I can't be more specific right now.
Using those figures I am mining about 0.105 BTC a month. At current 1 BTC = $827.33 on Bitstamp giving me about $87 a month.
I less than 5 months I break even. If the value of BTC goes up I break even sooner. If 1 BTC = $1000 then I break even in about 4.3 months. At BTC = $1200 I'm even in 3.6 months.
I am really new at this though, so I am probably missing something.
Thoughts?
Oh, and on a side note, everything I have read says Antminers require .5Amps, not 1Amp as suggested above. Of course this goes up a bit when I'm overclocking a bit under +20% I would guess, but not to 1Amp. Have I been misinformed (not that I worry about electricity costs at this time)?
