Got one.
Capable machine, with a weak spot in both the main and tail motors.
Great lifting capacity, pretty fast (for a 4ch heli), utterly incapable of banking left.
If you've got the space (it likes alot) then it's a good bird.
Can be bought cheaper if you're prepared to wait:

This is the old model now. There is a brushless version out which obviously solves any potential motor issues (that mine has never suffered with)
