It's been a couple of years but I purchased one that includes the mounting hardware and ducts to properly vent out of the front. My microwave model is Contoure CM11040BKT, which I purchased from dyersonline.com This particular model is 900 watts, very quiet, and includes all the mount and vent ducting hardware to do a proper install. $120. Worth it.
