Product review (5 stars): Don't think you need to spend more!
Looked at spending about 5 times as much, but went with this model to keep cost down on total remodel. Install was easy, just had to drill pilot holes in each side of vent hood as not able to use above mount pre-drilled holes.  The fan isn't super quiet, but neither is my house, and it's not too loud by any stretch.  It works as intended, and if it ever breaks I'll have the happy little feeling of knowing I didn't spend too much on it.
