Quote - zbrush, yeah about to save money for it. just a little bit afraid of the step learning curve and the resulting frustration. Blender is free, but without a rhyme or reason of the UI to me. Autodesk, I am not handsome enough, to earn some quick money,in order to affort it. ;)

zBrush has http://pixologic.com/zclassroom/homeroom/ to help make a stepless learning curve ,it's painless & easy to learn zBrush.
even in ZBrush System Specs they say Pen Tablet: Wacom or Wacom compatible.
if you ask on the zBrush forums they recommend.
http://www.wacom.com/en/us/creative/intuos-pro-m 
or better.
a lot use smaller tablets also.

Blender has a lot of tutorails and in a week or two ya get the concept of Blender work flow.it's easy and fun.
if ya going to use blender sculpting part ya need a wacom.

Blender works a lot like Lightwave & Softimage.
the good part is once ya learn a main app it's easy to pick up on any of the others.
