Hey Guys,

I've been researching bit coins for the past few days and can't believe how much things change on a daily basis. I'm considering to start mining, but yet so many people say that it's almost impossible. I've seen a bunch of units that are capable of doing 550 gh/s but are selling for 10k plus. With bit coin values dropping, I'm assuming my roi would be at least a couple weeks if bitcoin values stayed the same. In the past I've invested in stocks and sometimes have done well. Bitcoins is definitely enticing, I'm just trying to get in the right way. It looks like knc will be coming out with neptunes in a few months but their preorders sold out? 3th/s sounds pretty good, but diff level always increasing won't it be the same efficiency as the 550gh/s are today?
