there's something I want to address... I want to get into mining business, but the problem is that BFLabs has that problem of delays and uncertainty for the shipping date. I want to buy 5 rigs of 500 GHash/s each one, but to have nearly $120k USD stuck for how much time who knows...

Is there any alternative to BFLabs? One that that at least have shipping dates estimates. Many thanks to all.

There are USB ASIC mining equipment on ebay from the company ASICMinner called Block Errupter listed under which is in hand and able to ship imediatly however it is $150 per 333MH/sec which means it would take 2k to reach 5GH/sec. You can order a 5GH/sec BFL for 2.6k and have it shipped today on ebay. However with the price of Bitcoins droping it would be wise to consider profitability using bitcoinx before making a purchase. Also you can contract out your mining http://coinminer.biz/ offer a reasonable rate for a single year.

Kncminers are the most reliable in terms of delivery on time so far, I wouldn't buy butterfly anymore, I sold mine. Block Errupter is too slow 333MH/sec? you will not get back your money with that. If you already have some bitcoin, you can try cexio they do cloud mining for ~0.07 BTC at GH/s that is like 1/4 of the price of the errupter. Butterfly and Kncminers are a lot more cheap (not on ebay though) but there are big question marks on delivery.

Have a look at cexio as you will get a lot of flexibility on trading GH-BTC
