This is where I'm stuck.
The sculpt, a paint job by a good painter, shipping for all of that, is probably going to run what, another $350-400?
Just waiting out another Mace figure would cost less than that (but close), plus time. It might be better. It might not. Based on Dean Tolliver's track record, his Mace sculpt will be great.
Part of me would rather just buy the sculpt and get it painted and not have to worry about waiting for another version that may or may not be better. As we've seen with Luke and Obi-Wan, later attempts from Hot Toys doesn't always mean better.
