premium membership guides from SE0*M0Z

has anyone got premium membership to http://www.se0*m0z.org if so i have a couple of questions?

1) is it worth signing up for the tools or are there better/similar ones elsewhere?

The tools are:

Page Strength
Keyword Difficulty
Crawl Test
Term Target

2) do the guides have any "new" ideas or suggestions thats worth signing up to read them?

The guides are:

Social Media Marketing
Building Search Friendly Sites
Professional Keyword Research
Professional Linkbuilding

thanks in advance...

I used to have a membership. Not bad stuff. I've also got the guides. Which are well worth the price!

I have been a premium member for almost a year. I remembered reading 2 of the guides and found them to be too newbie oriented IMO. Will eventually read/download the other 2.

I use on a semi regular basis 2 of the premium tools. The others I don't think they are really unique. I do like the option to keep my past reports and data.

They also have a fairly recent SEO Analytic tool but I had no time to take a look at this yet.

I also like the private Q&A sections about SEO.

I can't say that it's a must have membership for me but I can afford it and it does save me time.

thanks for the input guys - will take a look
