That's not a bad price on those French ones. Can you access those from Amazon UK (I can't see how) or do you have to order from the French site?
I have a question about Mining Rig Rentals...
I can mine 250 ETN a day with my 3.7KH/s, which is worth about £17 at today's price. Why would anyone pay more than £17 for that hashing power when they could just buy the currency instead?
