Animal Atlanta will take the larger rats off your hands, so no worries about that. I'm also going to be checking out a local raptor society, like Jo says that use them for hunting their birds.
I've also placed retired females in pairs into pet homes. You do have to be careful not to say what they were breeding for before - some people freak - but I've placed favored females in some nice pet homes.
Really, do they buy them back or for just giving away? No matter what thats good to know if I have any big rats I need to get rid of!

Come here little guy. You're awfully cute and fluffy but unfortunately for you, you're made of meat
