I second Alex's recommendation for 200 Easy Homemade Cheeses. On the other hand, I also agree with Linux, in that I do focus on one type of cheese for awhile until I either am successful with it or realize I don't like making it.
I like having a book with so many different types of cheese recipes, though, because it gives me ideas on what I really do want to try next.
BTW, I love the commercial that your avatar comes from. Most commercials around here get muted, but I always have to listen to the GEICO ones at least once.
