Product review (1 stars): Welded crooked.
I bought a Kitchen Bath Collection 30-inch Wall-mounted Stainless Steel Range Hood with Arched Tempered Glass strait from kitchen and bath collection.  Shipping was fast and well packed. The unit looks nice, little noisy, but it pulls a lot of air, so noise should be expected.
My problem comes with the building and  quality control of the unit. As you can see in the picture, there is a base that has the filters and a rectangle that is welded to the base, an stainless steel shroud cover that rectangle. Ideally, this rectangular part that house the motor should be welded 90 degrees to the base.  Too bad, that is not the case in my unit. It is more like 81 degrees, so no matter how do you set unit in the wall either the stainless steel tower will be crooked, or the base will be crooked.
Price in their web site is around $300 with free shipping, hope you got better luck than I
