CUISINARTFP-8SV Elemental 8 Cup 8 Cup FP-8GM

Should i buy the 8 cup or the 11 cup? what is the advantage of one over the other? thanks!

Can i buy additional discs for this machine? french fry disc? whipping blade? citrus juicer?

Do the slices come out beveled or of equal thickness on the entire slice? Does this attachment otherwise work well?

I want to does this come with a case to hold the blades? From one of the reviews, her pictures show a case, but I don't see this listed specifically
