Are there any real differences in food disposal brands? The box stores sell Insinkerator Badger 3/4, 1/2 and 1/3 hp ones with one stage grinding as well as Insinkerator "quiet" models that have 2 stage grinding. The appliance store where I am buying new appliances sells Kitchenaid disposals 3/4 hp and 1/2 hp. The pipe that connects to my current Badger 5 1/2 hp model is very close to the disposal so I don't think that one of the quiet types would fit because they are wider, unless the pipe could be moved. Frankly, I don't really see the need for a quiet model because a disposal is only turned on for a few seconds, but hey, what do I know?
