I suppose it was just a matter of time--but starter sets are now available! Not just battle boxes--but a starter box meant to get you into the game: 2 armies, 1 small rulebook, dice and a ruler.
The starter shown gives you:
Khador starter box (Sorscha, Juggernaut & Destroyer) but adds a full unit of 5 Man-o-War shocktroopers.
Protectorate starter box (Kreoss, Crusader, Repenter, & Vanquisher) and a full unit of 5 Cinerators.
Best yet, for all you metal haters: It's all plastic.
$99.99 price per the PP website, or probably $75.00 at your preferred online retailer of choice.
Edit: The starter sets come out to (I believe) 20 points each. So more than a mangled metal 15 point game, but less than the 35pt standard most people seem to play.
