If there's one thing I've learned from reading the RPF, it's that "accurate" means basically nothing, yet at the same time, means everything. If you want an "accurate" prop, say, a Vader helmet, you need to know if you want it from Episode 3, 4, 5, 6, Rogue One, the Holiday Special, a "personal appearance" Vader helmet like the one in the current Prop Store auction, or any other appearance. Then you need to know which scene you want it from, since several helmets were used in each movie. Then you'll get people telling you that it's inaccurate and sending pictures with red circles and arrows, while others tell you "no, it's screen accurate for those 3 frames where Vader..."
And then you ask for a licensed, mass-produced prop (or TOY,) expecting total accuracy, for $100.
Don't get me wrong, it's fascinating to me to read how people scour flea markets and swap meets for that one type of wire connector that was used on a prop, that was only made for a week in 1973 for Soviet nuclear submarines. I've found parts like that myself. And people have made perfect recreations of props using duplicates of the original parts. But for the most part, compromises have to be made. There are safety laws for things like helmets. They have to fit someone other than David Prowse. Your kids still need to go to college. For probably 90% of people, "good enough" is good enough. I build models, and lately I've been on a "out of the box" kick. I've been obsessive over getting detail sets and painting every switch and rivet, and I found that modeling had pretty much stopped being fun. So I have several stalled projects. In the past year, I've finished more kits than I have in the previous 5 years, because I allowed myself to say "that's good enough. Moving on." If you want to obsess, obsess. If you want a Vader helmet to throw in a Detolf for the next 20 years, it's okay to get one that looks good to you.
