Seo ellite is horrible, I suggest the free version of webceo6.0 greek39
In the free version you get a whole wack of options, page rank, link pop, optimization advice, who links to you, and lots more. But some people download the program and I guess find it a little confusing. But once you get the hang of it I guarantee you will kick yourself.
I have used seo ellite, IBP, and some others, but nothing comes close to webceo
