Bitmain Definitely Listened this time, IMHO....

Wish it could be a bit cheaper but

S4: 2000GH @ about $1420 (Shipping Included + 1400W PSU)  $0.71/GH
----------------------------------------------------------------------------------------------------------
SP20: 1700GH @ $1309 (Pre-Order Shipping Included)  $0.77/GH  WITHOUT PSU
----------------------------------------------------------------------------------------------------------
AM Prisma: Price varies & Does not come with PSU


And if Batch 1 customer wants to buy B2, they will receive $50 discount coupon,
so it will be $1370 ($0.685/GH with PSU & Shipping INCLUDED)

Also, the cusotmer who has not yet used $200 coupons from S2 purchase history,
that is another $200 discount on top of $1250 price.  ($0.61/GH)

Another Benefit to "NOTE" for Bitmain Antminer Products...  If you are in North American Region, RMA is handled within USA, if you are in EU, RMA is serviced from either UK so no double tax.

Russia & Former Soviet Union Countries...  Buy these at your own risk, as your customs may not like these miners.
