When will you state your AM affiliation in your signature? It is fair for everyone to know, just like they see in my signature my affiliation to SP-Tech.

When I participate in the signature campaign and get paid to do so. Will that change the maths though?

SP20: $1,190.00 + $300 PSU for 1.7 Th/s = 0.88 USD per Gh/s
SP35: $3,920.00 for 6Th/s = 0.65 USD per Gh/s
S3+ B9: 0.58 BTC @ 453 USD/BTC + $50 PSU for 453 Gh/s = 0.69 USD per Gh/s
Tube: 0.889 BTC @ 453 USD/BTC + $100 PSU for 800 Gh/s = 0.63 USD per Gh/s
10 x Tube: 7.9 BTC @ 453 USD/BTC + 10 x $100 PSU for 8 Th/s = 0.57 USD per Gh/s

Given that you don't try to refute my argument that the SP20 provides terrible value, do you agree with that statement?

Really you only need an EVGA 1300W PSU and they are around $180

Which would take it down to 0.81 USD per Gh/s and makes it:

24.62% more expensive per Gh/s than SP35,
17.39% more expensive per Gh/s than S3+ B9,
28.57% more expensive per Gh/s than a Tube, and
42.11% more expensive per Gh/s than a 10 Tube set.

In other words, it still provides crap value and that's without the shipping fee.
