Pardon to butt in, but Coronas are anything but "boutique". In Bolivia you can buy them with worms inside !!
Seriously though, I have the bar you mentioned Newbee, and it's a below the bar depower which is a pain IMO to adjust. The kite has a very unusual default shape that makes it look more like a bat's wing. Not something that is standard in the industry. And self landing them is almost impossible, plus the shape of the tips catch water more making them hard to re-launch.
I think around $300 - $350 tops, for it's age too.
You can get 2012 kites for under $500-550
