Hello Bill,

The price tag is around $50k.
In my experience mirror prices are approximately proportional to the
*cube* of the diameter. So very approximately:
	16" => $ 2,000
	20" => $ 4,000
	25" => $ 8,000
	30" => $ 15,000
	36" => $ 28,000
	43" => $ 50,000
Going from 30" to 36" may seem a small step, but it will double your
budget.

Hello Robert;

As I too am thinking about a BIGGER scope a year or
two down the road, I am very interested in following
your project.  Am curious, if its not too personal of
a request, what was the price tag on the cellular
primary blank?  While mine may be in the 30-36" range,
your cost would put things in perspective.  I guess I
could always ask the fabricatior....

Thanks

Bill Marriott
