Before I gave up trying astrophotography in light polluted Geelong, and sold off all my premium stuff I had a Mesu 200. No tweaking, worked perfectly out of the box (crate :-) !!. I always got guiding as good as the atmosphere allowed, often as low as a TOTAL .15 arc seconds when the sky allowed. Pointing was exceptional. No one believes me, but plate solving would often put pixel on pixel, and I NEVER had a solve more than 3 pixels off......
If perfect guiding/pointing is what you want, I could highly recommend one.
FWIW
