Thanks for the input! Some of her work is manga-style, and some of her frustration is in trying to get the 'inking' line thickness more uniform, i.e., effectively turn *off* (or down) the tablet's pressure sensitivity. (I am thinking there must be a software control for this...) I have avoided Manga Studio because it seemed like there was some value in learning a less-specialized program, but maybe we should take a look.

In any case, it sounds like it is worth exploring the software further first before upgrading the hardware...
