Reflector huh? Dob mounted or EQ mounted?
There's plenty of dob owners around here, and a few with reflectors on EQ mounts.
Do you want it for visual or astrophotography? Do you live in dark skies or will you need to travel to dark skies?
The best high quality is probably achieved by getting a custom made mirror and put it in a tube. For "off the shelf" quality, you'll have to import an obsession or similar.
Readily available in the country are GSO and SkyWatcher newts.. both are quite good quality for the price. The mount can add extra to the cost, if you want a solid EQ mount to put it on.
So give us a bit more info about what you plan to do and we can help you some more!
btw where abouts do you live?
