Olicve wood is great though it has been a while since I have turned it.
I got my first at WC but it's not as nice as most of what I see here.
Another wood that turns as easily but with more wild grain pattern is Bocote.
If you can pick up wider piece rather than plain blanks and cut your own blanks on the bias or cross cut the effect is striking.
