You're probably right, it's not really worth arguing over. As I said, I'm no expert on Firefly props, although I've learned a lot since joining here and Fireflyprops.net.
A lot of that I've learned from Karl, thanks not only to his amazing collection, but his willingness to share knowledge about it. And what he doesn't have, he pretty well knows the people that do, so if he says this holster is the ultimate in accuracy, I believe him.
As to price, I can only say here what I've said over at FFProps, which is while I tend to agree that I can't afford it at the moment, I'm not going to say it's too expensive, because someone out there will pay for it, just as the guys over at Dented Helmet will pay for all the more accurate Boba pieces. Just like guys over at Club Obi Wan will pay for ever more accurate Indy pieces. I could go on, but you get the picture. In it's own way, Firefly has a hold on some of us just as Star Wars, Star Trek, Indy and other iconic franchises have a hold on their respective fan bases.
Even Doctor Who, which I also love.
