Some people name their scopes, some don't. I know people who've given their 60mm refractor a name. And a 20" newt is an APO. In fact it's better than an APO because every wavelength of light will focus at the same spot, not just three.
And once you get into the 6"-8" APO territory where you have a hope of seeing deep sky objects, albeit quite dimly, you will find that the cost function is parabolic, not linear.
