I read a Project Gutenberg version, but Part II is really hard to find online, on a fluke the day I looked I happened to find a completed copy, but it appears the addition I had read is no longer avialable online. I am a afraid I cannot recall the translators name off the top of my head.
I hear that Walter Kaufmann is supposed to be a good transtation.
A lot of people also really like David Luke.
Herold Bloom recommended Stuart Atkins.
