Matt, something to bear in mind... for planetary imaging you're only using the very centre of the image, so off-axis errors like coma etc don't ever apply as you'll never see that part of the field in your camera.
You should focus your thoughts (so to speak) on a design that gives the best on-axis image, quite different from the wide-field designs like the meade RC.
Even with a simple newtonian scope with a small secondary the diffraction-limited field is several times larger than the disk of Jupiter, so as long as you're collimated properly then you'll be seeing the best image that you can get.
cheers, Bird
