Many, perhaps most, programs have a magazine option. You can get AA's list of magazines here:

Whether or not you like any of them is, of course, up to you. (I couldn't compare the lists easily, since AA's are all in one list and CO's are split into categories that makes sense to them, so I can't say how the two compare.)
