Hi, new to the forum.
Not sure if this is in the right place or not but feel free to move

My boyfriend will shortly be finishing off his CCNA certification and then will look at completing his JNCIA. He seems to have a real keen interest in learning about networking.
Because of that I want to get him something relevent to help him with his studying or something IP networking related that would be a interest to him (magazine subscription maybe?)
I've seen a couple of books about JNCIA I was thinking about whch I may get but just wondering if you guys have any ideas? I don't want to spend too much (£50?) so hopefully there'll be something suitable.
Thanks in advance
