Best "Thus Spoke [Spake] Zarathustra" Translation

[PierceAndPierce]

I know there are many Nietzsche readers in this forum. I've recently been looking into reading "Thus Spoke Zarathustra." However I can't decide on which translation I should read. The two translations / versions available at my bookstore are:

1) Penguin Classics, translated by RJ Hollingdale
2) Wordsworth Classics, translated by Thomas Common

My limited understanding of English translators of Nietzsche tells me that Walter Kaufmann is the preeminent translator of his work. However, I did not see a copy of his translation at my local bookstore. However, I do want to know if 1) there is a Walter Kaufmann translation, and 2) Is that the best translation out there?

Thanks a bunch. And sorry I do not have much informative to say - yet.
