Limited edition pieces like these always instantly surpass the RRP immediately upon release, it isn't unusual. It is pretty much always people who missed the original pre-sales who are forced to pay the higher prices, because everyone else got in early.
Mine is still 100% without problems, still adore it and have it on display, albeit with the horrible double stand. I have a cat who has a habit of scratching his face on the ends of the nacelles, and I'm pretty sure he'd knock it over without the extra stability.
