I am just busting your chops... i have no clue what it takes other than what you say... have a good one and annoy a democrat today!
At $8,0000,000 per line that's 1,000 days of payback at only $1 per brick additional margin, or just over 2-1/2 years.
I promise you, in this market you could have been getting $5 per brick of margin no problem for the last three years. That is a six month payback, or a total of $20 million of additional profit over said three years.
