Reading all this and watching this thread here and on the FISD site, I have come to a single conclusion: There are multiple reasons for this issue and the divided camps.
We are not all in this for the same reason
Some of us are in this for the trooping experience. In fact, I think 99% of the guys and gals I have met in my short time with the 501st indicates that this is not about putting on the best armor to be a braggart, but trooping with a purpose. This is why I joined, and love trooping. I was once told that a 7 year old could tell the difference between a TE2 and a n FX helmet, and tell me all the things that were wrong with the FX, but I have never met this child. The kids (and adults) I see trooping love the armor, regardless. In my 5 days trooping Celebration IV, I had one person, ONE, tell me my new bucket was the first screen accurate he had seen , and wanted a picture with me. The other 100 or so pics I took, no one cared. Now, do I want more accuracy in my armor; sure, but that is just me, but at the end of the day, all I really want is to see the smiles of kids and adults from behind my green tinted lenses.
As I said, there is a second camp here, and these are the prop makers and collectors. This group is not into the Star Wars world for the kids and adults at the troops. They are in it for the chase; the thrill of having the most accurate helmet, or blaster, or armor out there. And many of these people have the means to pay for said items.
Now we will see crossovers between the two camps, but in the end, you really fall into one or the other. The challenge of all this recently is the "troopers", are becoming more savvy, and are looking for more accurate products, but they still do it for the troop. Sometimes the desire to troop in a screen accurate set of armor is not possible for financial reasons, so they look to people outside of the prop makers and uber-accurate collectors.
I believe now that it will be very hard for these two different camps to ever see eye to eye; the motivation is different, even if it is not financial. For me, I was thrilled I had someone comment on my bucket, but I would rather see the smiles on 1,000 kids who got to meet a Stormtrooper, than to know I made one 35 year olds day by having a screen accurate bucket.
I too want the "cool stuff", but I cannot justify the costs. I will just work and tweak what I can, and be thrilled the next time the seven year olds I meet come up and are so excited to meet a "real Stormtrooper", which, regardless of who's armor I am wearing, I am.
