I have beginners in our club do a 6" mirror for their first project.
We shoot for a focal length of between 40" and 48". That results in a
scope that is still easily portable and avoids the problems of figuring a
faster mirror. The good old 6" f/8 is still a great all purpose
instrument. A faster first mirror is asking for trouble. IMO.
As far as kits go I wouldn't know. Our club keeps a stock of 6" blanks
and the grits, etc. Good for us, but doesn't help you.
Newport has a reputation for poor service, Willman-Bell is expensive.
