CCNA Service Provider

in CCNA & CCENT
Thinking about taking this to renew my CCNA. Not much on here about this lately. Anyone taking the exam recently? Thoughts? For reference, I currently work in the networking group for a service provider.

Too bad Cisco does not have books for this track seems they don`t like us SP guys lol.
I have the CBT videos and I have also purchased a book on Amazon (CCNA SP ExamFocus Study Notes)?? Now that I have it, it looks like a non-official book. Its basically a cliff notes version of CCNA topics. Don't think it going to be helpful or go into any detail.
Any others books or material I should look at? The SP looks pretty similar to the R&S so far.

You can get through CCNA SP pretty easily using the CBT nuggets videos and google anything else in the exam blueprint.
For CCNP SP your going to need a ton of books.
