I used the iOptron for a short time but found it a complete PITA. Too many screws to tighten (and one always seemed to come loose) and you can’t easily adjust it in RA or dec. I sold it and and now use my DSLR plus small refractor on a goto mount which I originally used for a Newtonian reflector. You might like to think about something like the Skywatcher EQ mounts. Don’t skimp on the payload capacity though.
