Good Morning Folks

I am just getting back into my Network+ after almost a 5 year break

In all honesty I'm quite rusty.
The current literature I am using is Mike Meyers Network+ 2nd edition which I purchased in the tail end of 2005. How much has changed in the latest editions and is it worth me buying the latest edition which is the 3rd (or 4th) I think?
Also, does anyone have any experience with the Mike Meyers books? Any recommendations for a better alternative?
Any help is greatly appreciated.
