I bought the Toybiz Sandman and thought the head was goofy and the paint was lacking. I bought the Marvel select Sandman, but I thought he was too tall and the head was too passive for his cool accesories. Then I bought the Marvel legends BAF and I thought he was too bulky. So I Just mixed and matched to make my ideal Sandman.

I took the toybiz legs (to make him shorter and I like the color)
Select arms and body (I love the sculpted lines and accessories)
And the BAF head (the sand head works great with the power accessories)

It turned out pretty well. I may paint the neck to fit the head a bit better, but it's not super noticeable
