I sold my Nurgle demon army about a year ago. Now I really want to start playing again. I am a person who prefers to have all my models painted before they hit the table. As much as I love Orcs & Gobbos...it would take me forever to paint up the army for play. My time is limited with 2 jobs and a son so...

I was wondering with Ogre Kingdoms, Deamons, Chaos, Mortals, heck even Orcs and Gobbos...

What is a strong usable Army that can be painted and prepared in reasonable time?
