My favorite brewery supply place now is offering a series of cone bottom fermenters. Kind of like big plastic funnels on a stand. Their ad talks about not needing to transfer from a primary fermented to a secondary. Just drain the dead yeast off the bottom of the cone with a valve that is there. When ready to bottle you apparently can add your priming sugar and bottle directly out of the thing. No need to transfer from container to container.
Anyone using one of these? Likes, dislikes? Problems?
