I was starting to give up trying to get one in the AH so decided to try my luck in Hell Act 3. 5 mins in and a Homunculus drops in Level 1 dungeon.

38-62 damage
111 int
107 vit
35 AR
Reduce Cooldown 18 seconds zombie dog
Reduce Cooldown 20 seconds gargantuan

Don't give up guys if you haven't been able to get one in the AH. Bloody things are way too much gold! Do some boring runs or help people level to make it less boring.
