Big Dob Mirrors

Hello to all:
I'm looking at mirrors in the 24" - 25" size for a project, and notice a fairly wide price range for professionally finished optics. Companies such as Woden and Pegasus seem to sell them for thousands less than Galaxy or OMI Torus. All these companies so far as I know are reputable, though not all appear to describe the same testing methods (Zygo Interferometers are expensive!)
Certainly not wanting here to disparage any company's quality! Just looking for some reactions as well as experiences anyone might have had with large optics from any of these ...
Regards,
Randy.

Of the ones you mention, I would recommend Pegasus. John Hall is an excellent mirror maker (he trained Carl Zambuto), and a nice guy to work with.

I have heard good things about Woden, although on smaller sizes than you are considering. No personal experience.

Kennedy as other have mentioned is building quite a reputation as well.
