Where can you find a valid copy of zbrush for $150? Do you have any links to reputable software vendors? (E-bay doesn't count, as software from there is always a risk).

Since the OP has already stated she can't get zb right now, I think her best option would be something like Blacksmith3D. It has a $20/mo. subscription fee if you dont want to or cant buy full price up front.
