I've read A Babies VS X Babies online - you can get it on Comixology, think it's something like $1.99 - but you can't find a copy of the physical copy for love nor money! (Well, maybe money, but too much money, heh.) I love the Skottie Young stuff! And his variant covers are usually the same price as the normal covers, so I now get those instead of the normal ones whenever I see them *grins*.
