Anyone know a reputable place to buy these?

I got a local reseller from China, whose price is cheaper than the official website, and they can declare lower value for me to decrease or even avoid tariff, very reliable reseller.
They also have facebook group -"Asic miner buy& sell", where they will update daily price and show machine testing video.  
u can send inquiries to her if interested, highly recommend , below is their contact information:

zcash mining difficulty spiked today at an all time high.  But now is back down low.  Looks like a lot of Z11s were delivered or else somebody in China is testing a lot of them before shipment. 

I also got hit with a $2127.01 charge from Fedex for the Trump tax on 4 units. 

So high the tariff was . i paid no tariff for my 6 z11s as my agent in China declared just 95usd per unit for me. 6*95=570usd only, it's really good.

U can also ask my agent in China to help u next time, they are miner reseller in China.

In the US there seems to be a number of Ebay listings for Z11 preorders, though you're going to pay a pretty steep premium through those sellers as they jack up their prices due to import fees and PP/Ebay fees. Ebay provides you with very good buyer protection so there shouldn't be issues with buying on there unless you're buying from someone with 0 feedbacks.

You could also make a WTB post for a Z11 in the Computer Hardware section (click for link) on this forum. Always use escrow while buying and selling here if you choose to go this route.

it is best if you live in the united states to establish a gray import through canada. it will be so much cheaper than buying it in ebay. in addition, defective shipments are often sold in ebay.
which after a few months of work break down.

Hey guys, there are also many miner resellers in China, i highly recommend my friend Grace zhou from "Shenzhen Rumax technology limited", their price is lower than official website and can declare lower value for me to deduct or avoid tariff. They can also test the miners for u before shipping in case of any defective parts of miners.

How much was the z9 from bitmain, I remember ordering one then getting hit with the tariff, lol.

The price from my China reseller as below:
used Z9mini with psu: 194 usd
used Z9 with psu: 567 usd
Used A9 with psu: 895 susd

i think the difficulty of equihash mining will increase again when A9++ comes out.

I had to cut a check for 31k for the tariff on my z9 mini's. Worst decision I have made in crypto was to buy these. Should of just bought some masternodes

I'm still not sure what to order Z11 or Innosilicon  A9+ . The last is a bit costly and has a little less hashrate  (120Ksol/s vs 135 120Ksol/s) but, the way I see it,  A9+  is more  robust and relatively simple  to carry out prevention measures in regard of their long-term maintenance. Has anyone a difference   of opinion with me on that?

How are they with payback?
Do you believe that you can pay back the miner and still earn money on it?
Maybe it would be better to buy bitcoins right away?
It looks more win-win than buying an ASIC.
