Mark's mirrors are very well priced against other top US mirror makers.
We are talking world quality here. I won't put the price on here because it's Mark's business.

I have noticed that it is very hard to find a ready made 18 point flotation cell for such a large mirror(or any cell for that matter). Same goes for the secondary  ?????
What gives here?..............do I have to make these ?.............if so, any links? 
B.T.W...............how much is Mark's 16'' mirror? |
