Just bought the Sibwings Safir, late in the day I know, but from what I hear I wont regret it.
Appart from the purchase/support side of things, I seem to remember some sour tastes in the mouth from some members here. Guess I'll find out shortly.
Looks like I have to purchase the FSX version, then retro-grade to FS9 for free. Good move I think as FS9 users seem to be offered a free upgrade to FSx on release. Sounds like a dev with the usually elussive common-sense gland working. (okay, I'm not opening a can of worms, I appreciate paying extra for an FSX release if it is ACTUALLY updated to FSX SDK standards, otherwise, forget it, lost punter*.)
*granted, exceptions will be made for my FAV devs, heck I'm a human too, like some of my fav devs, lol.
