Opinion on Gotch SEO methods & services

[scienceisrad]

I would love to get you all's take on Gotch SEO.  I am gearing up to link build for a site in the next several months, and have been reading up from sources other than Moz, in preparation.  (Need to re-read Moz's guide, too, but I have already read it last year)  I'm reading Gotch SEO's main link building method articles right now, and am wondering what you all think.  Do you think they have a good approach and are generally reliable?

Likewise, has anyone used their service for getting a link?  What was your experience?  Or if you haven't used the service, any quick takes on it?

Never heard of it but I'm intrigued. I will go and check it out and hopefully be able to give some valid input!

Cheers
