The only deal I see from BFL close to that is 300GH for $1500, and that is a preorder for 3 or more months from now. This is what their description shows "Pre-Order Terms: This is a pre-order. 28nm ASIC bitcoin mining hardware products are shipped according to placement in the order queue, and delivery may take 3 months or more after order. All sales are final." So since difficulty pretty much doubles by the month, you will want to do your calculations after doubling current difficulty 3 times. If your plan is to mine and wait for the price to go up then it would be worth it as long as the price does go up.

Has mining BTC lost its profitability due to the high difficulty? Can people even break even with current hardware prices and difficulty level? I mean current hardware as in hardware that you can use today.

I see a lot of the powerful ASICs that can get you a lot of Bitcoins are all for pre-order right now. Since they won't be available for a few months I'm not very interested in them. A lot of the ASICs available for purchase right now are not very powerful and I'm not sure if they'd be worth the investment. Does anyone know of a seller that is selling ASICs available right now for a great deal?

Thank you for the information. I'm glad I can now post on the rest of the forum 

This is my first post and I'm still learning about bitcoins. I have 2 block erupters mining at 671Mh/s. I joined this forum to learn more about mining bitcoins. I'm currently researching what hardware to get next. I was thinking about Blackarrow's since they have a pretty decent price per Gh/s. They do have a reseller here in the US called minersource, but I'm not sure how trustworthy this brand is since they seem to be pretty new. Does anyone have nay advice? I was also looking at the rate at which dificulty rises and with this pre-order market it looks like the dificulty might be kind of high by the time one gets their preorder. That worries me because I'm trying to get into this to make some extra money.
