Ping-o-matic alternatives

"This is interesting," writes Kevin Burton at FeedBlog. "More meta-ping servers are coming at a fast pace. Looks like we now have Feed Shark, King Ping and Blogomatic."

See also Ping-o-Matic (which I've used and seems very good) and Pingoat (looks like the best to me). Blackhat SEO has a free blog and ping script (like to know if anyone's tried it and if it goes with Blogger).
