For Star Wars, I picked up HT Jedi Luke, and when the Mando version was released, I picked up the head, gloves hands, black cloak, and Grogu, all parted out, so I can keep it at 1 Luke, but two looks, and an improved head sculpt. For Vader, I've been waiting for HT to release a 1/6 ROTJ Vader for sooo many years, and at last that is about to become a reality. That has meant bypassing every other Vader release over the years, until this one. Sometimes you just have to be patient.
I also have HT Yoda and Palpy w/ throne, but am considering letting those go. As other have said, you're constantly reevaluating your collection, and one of the best things about this hobby is that most figures retain their value, if they don't appreciate, should you decide to sell. It's rare to lose money on a figure, unless of course it becomes damaged, or is over produced. The only figure I've ever lost money on when reselling is Endgame Iron Man, BD version. HT just made way too many. Hence why I am now staying away from MCU releases.
