Not really sure how much the company could be worth. I think $5.00 per share would be a fair price. If you look at the math that's already been done with regard to earnings per share, it's going to take a ton of machines to get any significant return. However, I do believe some large company would see MZEI as a long term investment that would bring it many happy returns.
Anything more then $5.00 per share is probably wishful thinking...pie in the sky thinking.
