Obviously you are entitled to charge whatever you want for it. And the free market is entitled to buy it or not buy it or debate about the cost worthiness or "slag off" the company verbally for their products being so shitty or overpriced, etc.

That's how an equilibrium is found, which will eventually happen with ASICS too.

Someone on this forum once said,
"i don't believe these miners are real. why would anyone sell a miner when you could mine with it and make $$$ that way instead." 

to which another poster replied, "because some people don't care about the profit but care about making the BTC network more decentralised and stronger and..." blah blah or someother socialist mumbojumbo.

That was a BS response. The truth is that 90% of the people selling mining equipment are charging 6 x what the device could mine in 1 month. In my opinion they are greedy. They are taking value out of the very purpose of the product. They get six month return instantly and negate all the risk onto the naive/greedy consumer. I certainly hope i am wrong and people do make a decent ROI or else the miner manufacturers and the whole BTC scene may have shot themselves in the foot.
