And a good thing to know, only give blue away if you trust your AP mid. I almost never give it away to randoms unless they are someone like Swain or Anivia who really need it and they aren't losing their lane.

If they don't flash, I never have a problem getting a kill with Phoenix. Also for a starter jungler, having that quick clear speed is a big +.
I've heard the new champion Diana is AMAZING and very quick at jungle. She is decently tanky plus lot of burst damage. Can jump to her target and also her E let's her pull everyone in like Oriana's ball.
I also have tried the new Evelynn jungle and she is also very fast. A lot of my friends who couldn't jungle before played her and were able to pick up jungling. (:
Nocturne is a good starting point, as is Nautilus and Maokai. All relatively easy to gank on as well as generally clear camps
Warwick is really easy to use and is a great jungler. Shyvana also a great pick after having more experience jungling.
And Swiftkid50. Warwick is a terrible jungler. He is great to learn with as he is a good baseline jungler to compare other junglers attributes to, he has good sustain, and hes, he is easy to use, but compared to most other junglers, he really isn't very good. No ganking power pre-lvl 6, and after lvl 6 his ganks aren't that much better then most other junglers. Slow clear speed, etc. He is good to start off jungling though.
