I think a NIB Stern Pro is a great way to start. The reason being there are a couple of great games available that work well in a small collection (Deadpool and Iron Maiden. You might also still be able to find a distributor with a Star Trek vault or Metallica sitting around). Also as a novice, you won’t have to do any work on either for a year or two. The biggest challenge to someone new is being able to look at a used game and identity any issues prior to buying.
