Clarins 230's best dupe

Dear Lacqueristas

Ever since I have seen pictures of the famous Clarins 230 aka Unicorn Pee, I fell in love with it. This particular polish is so hard to get that you have to pay a small fortune on Ebay to get hold of one.
People that own 230 claim that this next polish might be the closest dupe:

Nfu.Oh 51

Nfu.Oh 51 is close to Clarins 230 color wise, but of course this is a flaky whereas Clarins 230 is a sheer shimmer. A pretty polish nonetheless.

To those who own Clarins 230; what's the closest dupe you've ever seen? (If there is any)
Where did you find your 230, and is it really worth the ridiculous prize?
