As far as the equipment goes, the only other piece I did not factor in is cat 5, and maybe a switch (total less then $100).

As far as missed mining goes, that is true, i did not include that in the numbers, with 8 machines running, for 7 days, about 2 btc at the current difficulty. So that is about $1,000 minus electricity costs.

And configuration... that is extremely easy for these, so maybe 10-15 minutes of ones times, if you have never done it before. So I hardly would factor that in for the evaluation.

And overnight is great... but for this many machines, the costs are going to run someone a few hundred dollars based on the size and weight of these machines (if located in the United States).

So for the amount of time you lose mining by ordering thru Bitmain, and the cost of shipping, it would be slightly cheaper to order thru Bitmain (even with the missed mining time). However, you could always order thru his distributor in the US, who ships within 2 days via 3-5 day shipping included. They also offer overnight for a fee. And his prices on miners are also 0.893 btc. Therefore, that would be the "cheaper" route if you wanted it overnight or faster then bitmain. They would also be new units as opposed to used units for an unspecified amount of time.


And while it may be slightly thread crapping, I feel it is more of informing people who don't know better so they do not get taken advantage of. And since you are a newbie here at bitcointalk.org, alot of us try to help each other out. One way we do that is to educate people so they enjoy mining. Also, my post was to let you know that you are overpriced, in case you did not already realize it. If you want those type of prices, I suggest craigslist or ebay, where people can't be informed of these things.

Regardless, I hope you realize that I am trying to help you sell them, and not feel bad for overcharging people for used units. I hope you take this as constructive criticism and enlightenment, which hopefully leads to a mutual good deal for both parties.
