Oh yeah, hey there. The official sales thread for the server PSU stuff we build is at https://bitcointalksearch.org/topic/fs-gs-server-psus-boards-kits-stickminers-gpu-riser-power-made-in-usa-940317
I'm actually a bit short on the 2000W PSU itself right now but I'm working on finding more sources. I do have plenty of interface boards in stock if you want to test anything out. Feel free to ask questions.
Sorry I can't offer advice on whether to fetch an S5 or SP20, I have neither so I haven't done any comparisons.

chek2fire: I already have appropriate contacts at both companies, so I can weed out the scammers pretty quickly. I'm not likely to place a 6-figure order from a guy on a forum. 
philipma1957: Thanks for the links. Normally I'd search but that function is disabled.

no worries glad to do it.
either piece of gear is pretty good.
bitmaintech sells a 52 pack at a discount
sp-tech sells a 15 pack at a discount
Both companies will negotiate a bit on larger buys.
If you set it up let us know .
One more thing in favor of sp20 it you can list 8 pools vs 3 pools on the s-5.
sidehack may be able to get you good 2000 watts server psu's

Both of them has a great reputation in bitcoin mining world. Spondoolies i think has greater customer support and bitmain it seems that has a little better machines. Because you are new here be carefull for the scammers. I think already many of them has pm you and will say that the are from this companies 
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.

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
