What about the Block Erupter Cube 30ghs

Block Erupter Cube 30GH(220-250 Watts) or 38GH(320-350 Watts)

is no comparison to

16x Bitfury 25GH(25-30W) or 45GH(60-70W)

they use 8x more power and will be unprofitable to run 8x sooner.

When are the new 28nm gonna come mainstream

KnC 28nm Saturn/Jupiter was out Oct/Nov 2013 275/550GH (300W/600W) £3k/£6k 2nd hand, no longer taking orders (building a 20nm 3TH model)
HashFast 28nm BabyJet 400GH (400-420W) just started delivering last few weeks, suspended taking orders (4 batches already)
CoinTerra 28nm TerraMiner IV 1.6-1.7TH (1900-2100W) just about to deliver, $6000 still taking orders for May delivery.

Hmm, I would suggest SCRYPT mining instead of BTC mining with that ammount.

Like mrugala says, think about building a gaming PC and mining Litecoin instead when your not playing games on it.
