Hi,
The question is "will i want one?" At f4.5 many will whereas others can tolerate coma or are not as picky. I wouldnt
not buy the scope simply for not being able to afford a parracorr.

Also, I understand that most Paracorrs will deliver a magnification effect of about X1.3. Is it the mag effect alone that helps correct the image or other processes?

A barlow is not the same thing as a coma corrector. The 1.3x lengthening of focal length is just a side effect of this particular design of coma corrector.
