I did talk to them tonight and although I wasn't really too satisfied with the answers I got I have a slightly better indication of what is going on now. I believe, based on me pressing him pretty hard, that there will be a new batch that is available for us to purchase. That being said don't quote me on that since he was still rather vague. He said that they literally cannot keep up with the demand for the units due to the explosion of the price of Dash. As far as building a GPU rig and comparing it to the Baikal Mini.... That is like comparing apples to oranges. Different algorithms and currencies hash at drastically different rates and also GPU rigs are far more difficult than the plug and play nature of ASICS.
Thx for reply...I was just trying to get a rough idea...would I need 10 of the higher end gpu's to achieve 150 mg/h. I know it likely sounds nuts what I'm asking...nevertheless I'm searching and reading as I'm posting this.
You could build a 5-6 GPU system that would get you 150mh/s mining on the Ethereum network. X11 isn't as efficient on GPU as Digger Hashimoto, you'd be much better off mining ETH and converting through NH an exchange to get your Dash. Keep in mind that system may run ~1200w, a far cry from Baikal's amazing wattage.
