Rayma:
"a concern that fellow posters are calculating production costs of $2000+ seems simplistic."
I agree with that point you raise. The $2,000+ costs referred to in the most recent quarterly would include other "ramp-up" costs etc.
Thier current costs, however, are not $650-$700. Their goal is to achieve "just under $700" by December this year (from memory) if they reach their production targets.
