Good point! Why not just modify the newt! You will need the MPCC for sure and if the newt is collimated well it should give you pinpoint stars across your image. Also faster than the APO and RC!
I have also viewed some test results of the RC on a german site, not very pretty at all!
If I had to choose I would get a nice APO.
