Vanity Presses: Which Company would you say is a Vanity Press?

I admit right now, I do read a lot of blogs, but I tend not to comment, so there you go, but still on many there is a talk about publishing. Where you should go and where you shouldn't go... So I'll write down a list here and let you at it:

What I am trying to figure out is this: By their names which one is by reputation a vanity press and which one is more in line with a self-publishing press:


Xlibris

Outskirts Press

Random House Book

Create Space

Lulu Publishing


Here is my answer: first two-- vanity press, next, traditional publishers, and the last two, both are self-publishing companies, provided you have your own ISBN.
