2 extract brews and then I went straight into AG. My first AG is currently sitting in the carboy.... I hope it turns out OK.
My advice is to research AG extensively before jumping in. It can be a tad overwhelming at first, considering the added cost of equipment and a more involved brewing procedure, but I think it is ultimately worth it. You get the freshest beer possible because you are making everything from scratch, and your brewing will actually be cheaper in the long run. Extract is expensive to make so it is expensive to buy. An extract kit that would normally cost $37 dollars might be as cheap as $21 if you do an all grain version.
