In reality it's a marketplace issue. If there was a significant demand and you were selling millions of them, the price would probably be $400.00, but it's a niche market and how many are being sold per year? Maybe just hundreds.
To who?, AROs and SWLs, so the price needs to be high enough to cover costs and hopefully make some return in investment for the manufacturer. The manufacturer has set his price on what he thinks the marketplace will allow. If the price is too high then he won't sell enough of them to survive.
That being being said.... enjoy!
