Hi Dave,
I don't know what your local (hobby) telescope is using as a reference when he implies that GSO/skywatcher are inferior products, but just about all mass produced mirrors come out of either the GSO or Synta factories these days. My understanding is that even most of the Meade and Celestron scopes are made in China now (same factories?) Your next step up from that is to have a higher quality of mirror made for you by an optics specialist. And yes they will be better, but it's like comparing an average run-of-the-mill family car to a luxury car. You'll be more than happy with the GSO/Skywatcher, as is many other members here on IIS.
Don't be discouraged by the comments from your local store, Andrews or BinTel will also give you amazing service and support.
And seriously, what do you need in a Newt/Dob anyway? 2 mirrors, and a big round metal tube to hold them together.
