Beck's isn't that hard. Neither are any of the German lagers for that matter. Beck's uses two-row malted barley, German lager yeast, water, and Hallertau hops. You could do a mini-mash with extra pale malt extract replacing part of the grain. Check with your LHBS. They can set you up with a kit. Keep in mind that you are talking about a lager. You need a way to cold ferment and then the beer will need to age for six months or so.
