All in all I'm relatively happy with it.
Anyone wants to buy them from me? :-)
That quote would make a nice banner ad for your vendor.
You don't say when your original order was or what you paid. Until you provide those figures, we'll guess February 2013 and $60,000.
Your 1500Gh/s represents 0.0004 of the network today.
The network mined $900,000 today, which gives you $360.
Let's let difficulty increase 33% for each of the next eight 11 day periods.
Period one: $4000 to you (or your buyer)
Period two: $3000 to you (or your buyer)
Period three: $2250 to you (or your buyer)
Period four: $1750 to you (or your buyer)
Period five: $1350 to you (or your buyer)
Period six: $1050 to you (or your buyer)
Period seven: $800 to you (or your buyer)
Period eight: $600 to you (or your buyer)
So $15,000 to you or your buyer in the next three months, and $2000 in the three months after that, and $300 in the three months after that and dust after that.
So you're offering a machine that will print $18,000, minus the electricity. We'll leave BTC upvalue out of it, cause the buyer can buy BTC today and realize that profit.
What's a good price today for what you paid $60,000 for 8 months ago? How about $15,000? $12,000? $9,000?
Your vendor is asking $15,000 for the same product, delivered some time after March, 2014. That product will make about $2000 for its buyer.
BTW, if your vendor had delivered in February, 2013, when you presumably ordered, you would have mined BTC at 100 times the rate your machine mines now.
Finally, here is the moment when the BLITBU (or his sychophant) shows up, not to answer customer questions, or explain his company's delays, or aplogize for past delays, but to say, ".... if we had done what we said we'd do, all our customers would be just as screwed as they are now, which means we're a good company for delaying 8 months and more".
Last word: You are to be commended for offering a product in hand for sale, and not a preorder deal.
