I've sold one of my S3 miners, will sell my next one and a coin craft to help fund my S5. I was juggling between this and the jackson but I believe this is better on the wallet in terms of power consumption. I lost $19 AUD on my S3 miners which I ran for about 3 - 4 months but I'm not fussed, I made some bitcoin!
Hold your horses back! There's currently no way to buy either an S5 or an SP20...
Bad times truly .... tried to order an Avalon 4.1 and total comes to
BTC 2.14 including shipping with DHL to UK (not that there is choice of shipper either!)! What a rip-off! My S5 cost a whopping
BTC 1.1 shipped (after applying voucher).
Patience... i even got a loan on BTCJam to buy an additional unit, and Wham! No S5 for me
Good thing i have enough hashing power to cover the loan.... but this tests one's patience...
