Look, go to the mirror. See yourself in the mirror and say to yourself, "I don't like this little cherub model, and I'm not going to use it for my Marines. Now, I'm freed from the shackles of pointlessly collecting bits I'm not going to use."
Feel better? Sure you do. Now come back to the computer. Since you're not going to use that little guy, I'll trade you something for him. What do you want? I've got it all. Except for the l'il cherub melta-bomb carrier fat baby angel, which I need, which is why we're having this conversation.
