I may be in the minority opinion, but I don't like "sets" of router bits. I would recommend getting a few bits based on the projects you are doing and then add more. Start with a straight bit, a flush trim bit, a round over, and maybe a pattern bit.
I bought a 30 bit set when I started off years ago and realized that at least 30% of them were really not essential.
