Is there an add-on like AdBlock for Safari?

[rgG]

I just installed AdBlock in FF and it works great. Is there something similar for Safari. I don't use Safari much, so I am not that familiar with the add-ons. I saw several ad-ons that looked like they might work, but I would like a recommendation before I install.

I would like one that works like AdBlock. It should let me choose which images/animations to block.

Thanks for any advice.
