At risk of sounding like a 'sideshow apologist', I think people are missing a huge factor when complaining about the price. Any figure based on an 80s movie with an actors face will be more expensive than a similarly accessorized contemporary movie figure because they are truly more expensive to license.
These days when you buy a movie license the characters with their faces are included. Back 80s, actors retained the rights to their own faces on merch separate from the main license. Now anyone doing an 80s figure with an actor face has to buy the movie license to do the character PLUS buy the likeness rights to include the actual actor's face. (If you recall, Hot Toys had the aliens License with the characters, but not actors likeness rights when they did the Aliens figures).
Those extra costs show in our prices. Any talk trying to comparing a figure with a real 80s actor likeness to figures of faceless troops, creature figures, movie monsters with unrecognizable actor faces, video game characters, artistically stylized faces (looking at you ThreeA and DAM gangster kingdom) or figures based on movies this decade are not apples-to-apples comparisons. Those actor-free faces and contemporary figures truly are cheaper to make.
The reason so few companies tackle our 'vintage' icons is rarely that they "don't care". The hard fact is it is more work, more expensive and therefore a bigger risk.
If you want to complain about quality as it relates to your dollar, I am not arguing with you. Sideshow earned the right to have you doubt them. I am just saying the extra cost to get our icons made is a real thing, not just corporate greed.
