The Skywatcher 180mm Maks are outstanding. Mirror shift is very small, and eliminated with an external focuser if it's a concern for you.
Better still are Russian Mak optics such as Intes or APM. A 9" Mak does chew up galaxies!
You can go with Celestron or Meade SCTs, but you need to test these individually to find the really good ones. They do exist. My own Meade that I thought was a dud ended up just having the corrector plate retaining ring screwd on too tight which distorted the corrector and stuffed the image. Now it is really blooming good. Hell of a journey to get there. My Intes Mak still muscles it out even though it's a little smaller in aperture. Finding this Intes Mak showed me SCT's have a WIDE range of performance! Few are really good.
