Bigger is better (mostly).
I have had no problems with GSO gear, whereas a couple of skywatcher purchases have been less than optimal.
Just to mix it up......
The Zambuto comapny is now offering upgrades to the mirrors in mass produced reflectors.
Not cheap, at about $700 + postage. but worth the effort IMHO.
For those not familar Carl Zambuto makes what are arguably the best mirrors in the world.
