Yes, I have 8" Zerochromat and I am very satisfied with it. Zerochromat has an advantage - optic design is usable also (at the same time) as ADC for planetary astronomy.
Regarding ADC capabilities, how is it that the Zerochromat can accommodate for that adjustment? I ask as I've been keen to make some travel plans this summer to visit the Custer Institute Observatory out in Southold, NY on Long Island (~41.08° N, 72.47° W) for a look-see how their 10-inch model fares on the (low-riding) planets.
