The conversation might save you a pile of cash and a long wait.
The manufacturers that have proven track record of delivering consistently excellent optics include:
Mark Suchting,
Mike Lockwood,
Carl Zambuto.
This list is not exhaustive but not a bad start.
Incidentally, I believe that Peter has at least one, maybe two 18" mirrors sitting on the shelf ready to go (and at a very reasonable price). They have been tested and are of known good quality. If memory serves me correctly, they were made by Hudeck.
Obviously, I have no financial interest in any of this.

Hi Clive,
About Ostahowski's optics, I only can to say that I have one of his mirrors, and his performance is excelent. If I will buy another mirror, will be an Ostahowski's.
His interferometry numbers are very conservative and realistic, nothing of 0'999 Strehl. In the U.S. he has an excellent reputation, and his secundary mirrors are also much appreciated.
