user4535: 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.

user-1: 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.
