#1 - You get what you pay for in beer kits. Expensive kits are expensive because they have more hops, more malt and produce higher % ABV beers with more body, bitterness and hoppiness. Cheap kits generally require additional sugar and produce low body, low ABV beers.
A typical AS clone recipe runs 7-8 pounds of extract. Cheap lager kits 3.3 pounds + table sugar.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
