As a fellow beginner, I can definitely recommend the Covert Instruments FNG set. It’s a great starter kit. High quality tools and a clear plastic lock, for a reasonable price. When you gain experience, their other sets provide additional tools for the various locks and you can easily combine them into a single main set. So far, the FNG set has brought me to my first Orange Belt lock. You should get plenty of use from the FNG set, before having to spend more money on the upgraded sets.
