I am thinking that I will spring for a cornelius keg (~$30), however this is the first beer that I have brewed, so are there any reasons that anyone would advocate not doing so for the first time? Also is it still necessary to use secondary fermentation when you are kegging as opposed to bottling? Are there any guides that I can read on recognizing the tastes in beer, I am relatively new to beer and I really enjoy the taste of it, but it is hard for me to recognize and distinguish, aside from going out and making myself broke buying tons of beer (which I almost have anyhow), is there a guide that will do something like tell me to buy contrasting or similar types of beers and would describe the differences, so I can read and taste?
