Hey gang. I'm new here.

Quick background: My company has been in the financial tech space for 10y and currently processes about 500M transactions annually in the Gift/Loyalty space. We have an interest in linking crypto currencies, and that's what brings me here.

I have a friend with a company that has a 500 TH/s operation using the Antminer S5. We're looking at building something similar in the coming weeks, but after I started researching, I came across the Spondoolies-Tech SP20.

Looks like bang-for-buck has the SP20 in the lead, but I didn't know what else I should be looking at. I've tried searching here, but it's currently disabled.

Can anyone point me in a good direction?

I've ordered 5 S5s and 5 SP20s to compare the two.

Pros/Cons?

Thanks for the help. It's appreciated.

I have  multiple threads I will provide links

Hard to say what would be better for you.

 But if power is really cheap the sp20's can do 1500gh   

the sp20 can downclock to 900gh and use .46 watts per gh

the sp20 can overclock to 1500gh (even 1650gh with good psu's and good cooling)   and use .61 watts per gh       this large range of hash is nice.

the s5 can overclock to 1300gh and use .54 watts per gh
