i have the g3 4x5 and would love to have an intous of any size.
it takes no time at all to get used to the smaller size and while I would like a larger one I can tell you it’s not a hinderance to have a smaller one. I would recommend tho that you get the most pressure sensitive one you can afford…it really does make a difference.
I too would save for the 9x12 if ya gotta way to do it! But I personally would recommend you get the best you can afford now and save for an upgrade later. Why? because especially with zbrush it’s much more intuitive and easier. If you do more work in traditional 3d modellers then wait because a mouse is a mouse is a mouse and using one is not a big deal. With zbrush tho…a pen is the ultimate …no pun intended.:rolleyes:
