Do a google search. Depending on what you want it to do, anywhere from $600.00 to $160,000.00 (and they're called DVD duplicators).
Now if you want to replicate DVDs you're in the half million and up range.

I'd rather be ignorant than stupid.
Ignorance implies a lack of knowledge which is easily correctable through education.
Stupidity implies an inability to learn.
Therefore; ignorance is temporary, stupidity is forever!
