SHA256 ASICs are hard to make a ROI these days. I suggest purchasing a scrypt miner instead.
Check out gawminers!
Since KNC, is coming out soon, even scrypt might be difficult to roi depending on shipping times. Better asics are also coming out to the market.
True, true. But right now the ROI is really low and GAWminers are shipping soon.
ROI is going to plummet with the advent of ASICs comming to scrypt mining.
Yup, we will see a rapid rising in difficulty of litecoin (and doge and other scrypt coins) when the ASICs are shipped.
This is a good example of why it is difficult to ROI with mining as it is difficult to predict the future of mining technology.
The 400MH/s KnC titan will be shipped in Q3 (

It is really hard to estimate how the litecoin difficulty will evolve 3 months later.
With both of these machines, and similar machines on the bitcoin side of ASICs it is very difficult to know how many the manufacturers are selling and producing.
