All of my ‘beginners’ series build guides are self-found proven. Out of stuff that’s not too dated I have Blademaster, Dervish, Infiltrator, Spellbinder, Templar and another DK which is pet-based. I can recommend any of them except Pet DK, which is self-found proven too, but microcontrolling skeletons and still fighting close quarters is beyond normal player’s capabilities.
As for the list of beginner build guides you can check the Compendium, they are under the Builds for Beginners.
