Three other decent junglers (but certainly not the only ones): Predator, Puppet Master and Legion.
Advance apologies as I haven't played in a few weeks so some of the names of abilities escape me at the moment, BUT, the generic playstyle is correct.
With Predator, his passive ability that allows him to leech a % of health with every strike is his main staying power. His Stone Skin and Venomous Leap ability are also great retreat abilities when threatened as a jungler.
Legion as a jungler is a tad more difficult, but it amounts to knowing how to creepstack and making the most out of his counterattack abilitiy.
Finally, Puppetmaster is difficult but not impossible. Whiplash + Attack Speed items + Health Potions / Bottle allow you to take down large groups without much downtime inbetween. A nice thing about a jungling Puppetmaster as well is that he is an excellent surprise initiator, and if you're jungling you can flex across lanes to set up ganks easily. Two disables that are just as effective early game as they are late game can be devestating to low level players with less means of escape.
edit: I've forgotten the obvious Ophelia, but she requires a lot more micro than most and is pretty much assumed to be jungling when picked.
