No real flying time yet, but I bought it last sale and the first impression was really solid. No framerate hit, sounds are okay and it's artistically consistent. It also doesn't use any dirgital rights management (i.e. license keys), so it's less likely to have compatibility issues in the long run (or only minor ones that you can fix yourself). Can't go wrong for that price.
For other aircraft in the same vein, also consider MLADG's and VSKYLABS' aircraft.
