opinions anyone?

i got $130 to spend at mac for x-mas. my question is this, does anyone own the 231 shader brush & do i *NEED* it? i need something for really good blending (i have other blending brushes, but nothing i love...). cause $130 isnt really that much & there are a billion things i want/need if that brush isnt fantastic.
thanks much:)
