Just out of curiosity, I peeked at their website and clicked on the instructions for their American IPA (not one of the Brewers Best kits). I must say that in my opinion the particular set of instructions that I read through are typical of kit instructions in that they will get you beer, but not the best beer. I did feel that some parts of the instructions were just plain bad process. For instance they tell you to steep your grains until boil. That is a no-no. You should not let the steep exceed 170* or risk tannen extraction (water boils @212*).
Moral of the story, with more info there is much room for improvement.
