I'm very happy thanks
Many do require more than 15hrs to convert, that is true. But it's not unusual to see people with a lot of instrument experience do it in the minimum. If you're starting from scratch you probably won't save anything by doing an FAA and converting; it's only a sensible avenue for those who might have an IMC rating and several hundred hours. The FAA, being a whole lot more reasonable, give you credit for ALL your previous instrument flying whereas JAA are just dicks about the whole affair.
