You really have a very impressive collection indeed. And I think you are going at the right pace. Even awesome collectors like "Mad Bubbler" or "Robimus Prime" amassed their collection over a significant period of time. Some of the pieces that you have, like the Cats Lair with box are extremely hard to get. So you've already managed to snag some of the rare pieces. And I'm sure you'll get the remaining MOC figures sooner or later to complete your collection. And it always is a big plus to have loving family members who support and help you with your collecting.
