I dont have it personally, but my mate has and ive flown it on his a number of times.  Good model. he has a problem with the wheels, the way they tilt downwards when on the ground, as if not in contact with the ground.  Im not much of a VC flyer but it looks alright, however it does look quite based on the default 777 panel...

Im not actually a big jet flyer, well i do like the A340 but other than that im 757 or lower normally so i may not be the one to comment really. But if it were me i would go for something different, but again thats because im more of a smaller jet kinda guy

As far as alternatives go, perfect flight do one and there is an aerosoft/wilco 777 boxset floating around too.  BUT a lot of this will be meaningless drivel if you're flying FSX as im on FS9...


Hope ive helped somehow...
