The main reason I do this is because they are now offering the perfect dice set if you're an Orcs & Goblins player, namely Waaaagh dice with Orc Skull icons instead of 1's. I really like having unique dice when I attend games and tournaments, and so I absolutely love the ones they've announced and I eagerly placed an order.
If you're anything like me, you should really pick up a set of your own. While you're there, why not catch one of their episodes and see if they might be something for you? I find podcasts to be excellent company while painting.
Also, if you're interested in learning about other podcasts and reading a few opinions on them, you should check out Kuffeh's take on the subject over at The Trading Post.
