Ah, thanks for the background.
To be fair, 750 USD for 5.5Mh/s translates to 750/5.5 = ~136.36 USD/Mh/s.
Then * 18 = 2454 USD = 1450 GBP for 18Mh/s which is almost exactly what the Alpha-T costs incl international shipping.
So if anybody is struggling to find G blades used or new (presumably stocks are limited?) and believes Alpha-T will ship, there is still an opportunity here (given that there's some negotiating room here with us on 30% of the price).
