We have been using Maks for years. Originally the 127mm SkyWatcher, which eventually I managed to break a little and it was too heavy to carry around anyway, so we bought the 90mm one.
It has to be said that it has its compromises. The image quality will never be comparable with a top-end scope, simply because the optical system does not allow that for daytime observations, there will always be some parasitic light lowering the contrast a little. (Btw. this can be helped a lot by putting a long extension tube of a dark material in front of the correction plate (like a dew shield) - honestly why nobody offers this as a part of the telescope is beyond me, because the difference is immense. We just took a piece of flexible plastic and wrapped it around the tube with room for the tripod mount and now you can pull it front/back as needed. )
On the other hand, a Mak is insanely cheap for how good it is, especially for someone like me who already owns a large selection of astronomical eyepieces. The 90mm Mak costs 190 Euro and it beats the view by any lens scope at that prize point simply by having no chromatic aberration. That is a really big plus for me and the main reason to keep it. I could now afford a more expensive scope, but a scope that would measure to the Mak would be so expensive that I would constantly care about not leaving it in the car etc... where with the Mak, if it gets stolen, well, I'll just get a new one tomorrow, no problem.
I am not using a zoom eyepiece, because fixed eyepieces are much better. Considering the long focal length and only 1.25" exit of the Mak, using very low magnifications does not make much sense anyway, because you would have a very limited field of view, so I am mostly using the 35mm Baader Eudiascopic, which fully uses the 1.25" exit and gives me 35x magnification, which is also mostly enough considering heat haze. I also do not use an "erector" prism, just a 90 degree mirror - if you are watching from the top, it just flips left/right which doesn't matter at all; I have to admit that even though I know that flipping in any direction does not matter, I do have problems understanding birds upside down, so I prefer to observe from that angle, unless seawatching.
