Certainly Catseye and Glatter tools are top notch.
I have also found Farpoint tools well-made and accurate.
In combination tools, it's hard to beat Astrosystems or Catseye.
Even inexpensive lasers can have aperture stops added and be collimated to yield excellent results. BUT, many are undersized and fit the adapters sloppily. That issue goes away with a Glatter Parallizer adapter, as does the possibility of mis-registration of the adapter in a 2" focuser.
