Don't want to change the subject, I advise any prospective buyer to use escrow and mainly to use common sense.

I do have a separate point though: price/profitability.
I know you guys are mining just for the sake of the network and in "ars gratia artis" terms. But these will never break even mining at 3Mh with 90W power consumption, at 0,1$/KW, which are all very optimistic.
And don't tell me you will be also mining SHA, because at that hash/power consumption it will lose you money from day one.
At a 3% difficulty increase you will be 1500$ in the red after ~500days. Do you need to wait that long to find out you've lost 1500$?

And we all know that once ASICS get in, the diff will explode. Bitcoin has about 25-30% steady diff increase. But the first Bitcoin ASICS, whoever got them first were sold at a price that could be recouped in 30 days or less. Gridseed, as it is priced right now does not break even!

My point and message to you, seeds is that your price is too high. Especially in the current Crypto market.
Please price it at a level at which the miners can make a buck, at least a small one.
I'd buy if this would have a max 90 days breakeven time.
