Terry - Thanks for looking in.
Your question on resin is somewhat complex. Some people stay away because of the cost for sure. Others who look for "mainstream" vehicles can find the in styrene. Quality variation is another issue. Some manufacturers like Real Model or Hobby Fan produce excellent quality kits. Others are not as good and lack detail, they also are a major task to clean up and fix molding problems.
While most modelers are not afraid of resin figures or AM kits, an entire kit can be daunting and if they are looking for just mainstream, they don't need to go there.
Heavy show people I also think shy away from resin kits. a resin kit is percieved as more work and may not "do" as well...again going back to mainstream.
I have a "number" of resin kits on the shelf but I am a modeler who has a specific area I work in, US artillery and support equipment from WWII to present. Many of the subjects I want, like this one, will most likely never be made into styrene. I also never started modeling again to win medals. I go to shows but recieve enjoyment just showing my work and watching the faces of the people looking and going "hummm, whats that, never seen one of those before".
Lastly, I think it is fear. Many people are afraid of resin and comfortable "in their zone". Everyone is different. I will try EVERYTHING...once, "you have nothing to fear but fear itself". For all of those who are not into resin, I still have the utmost respect for their work.
It's like music, country, rock, pop, jazz, blues and classical but its all still music.
