Hi Joe,
All I can do is iterate what previous posters have written.
Mark makes world class mirrors. See
http://deepsky.cia.com.au/optics/
There wouldn't be too many star parties in Australia where you wouldn't find
one or more of Mark's mirrors in use.
See also recently on this forum

where Mark's mirrors were commissioned by some discerning customers in Texas.
