Where can i find an iMac with a built in CD-drive?

So i am looking to buy an all in one for my parents, and i think the iMac might be the best option, i know they will be using a cd drive quite a bit so i would like for it to be included instead of having accessories like the superdrive to do the job. and besides i dont think they care about the extra power or thinness of the new iMacs. I cant find them on their online refurbished store so.. does anyone know where i can get one of these?
