Most of the mirror flop in the meades can be dialled out by adjusting the main focus knob. Just undo the single allen screw and turn the knob clockwise until it becomes tight, then back it out a touch and tighten it up. The rest is taken care of by the mirror lock and using a crayford. I haven't seen any spot diagrams for the LX200R/ACF series but the field is pretty flat with nice round stars to the edge but you do get some bloating in red (green and blue are spot on) when imaging. Both the meade 6.3 and 3.3 FR work ok but you need to put in a large format visual back in front of the crayford if you want to use DSLR or large format CCD as the original has an obstruction which reduces the 2inch clear aperture to about 1 and 3\4. I dont know if these are available for the 8 inch.
