Good news! I won a full frame mono camera with an 8 pos filter wheel

Bad news, now I need 2" filters and they are not cheap!
..and a bigger coma corrector, bigger focuser etc.
Most of my imaging is NB, done from the burbs of Melbourne, 15ks from the CBD. I currently use 3nm Astrodon filters in my QSI 683 and have been very happy with them. I can pretty much shoot regardless of the moon most clear nights.
So having just priced a new set of 2" AD filters at almost $A6k
I'm asking the community about the alternatives.
Has anyone done a comparison between brands, are the Astrodons really that much better than the others available now?
Thoughts welcome.
