I need a bit of expert advice here. I'm thinking of buying a single-cup coffee brewer, but I can't decide whether it should be a Keurig or a Tassimo. I've read both good & bad reviews about both. The biggest criticism seems to be the taste, yet a lot of people say the taste is great. I'm looking for something to brew many types ..... espresso, capuccino, lattes, hot chocolate, regular coffee, etc .... Is there anyone out there who can advise??
