I used to drink stouts and porters pretty much exclusively; now I have been lured in by the hop... all suggestions here are great, Bristol Beer Factory ultimate stout is excellent as well for commercial, or Brooklyn Brewery's dark chocolate stout. Kit wise you can't go wrong with a coopers and can throw just about anything at it and not mess it up. I have done a few, including one with an additional kg of dark malt, 300g of brown sugar, and brewed to only 3 gallons, which was interesting...(ie extremely alcoholic)
