The previous posters have said it all..Rodinal is not the latest or greatest. It is cheap (like me), last forever on the shelf (no comments) and does a very good job. D76 (ID11) is the developer that most are compared to, Xtol, Pyrocat-HD, PC-Tea, are others you will see a great deal of here. Read all you can, learn the basics (I still am) and enjoy...no darkroom needed to develop a roll of film, so do it.
