If price isn't nearly as important as safety, quiet operation and longevity, reviewers highly recommend the InSinkErator Evolution Cover Control 3/4 Horsepower Disposer. Like other batch-feed disposers, it only activates after placing a magnetic cover over the top of the drain. This makes it impossible for fingers or objects to get caught in the blades during grinding. Experts say it grinds meat bones as quickly as the most powerful disposers, but with less irritating noise. For owners who expect to be in their home for a while, the durable stainless-steel blades and grinding chamber may be worth the higher price tag. Because no activation switch is needed, the installation costs will be lower in homes that don't have one pre-wired. Owners also appreciate the compactness of its 13.3-inch height as well as the ease of installing the Quick-Lock Mount. The manufacturer offers a seven-year warranty with in-home servicing. If you are willing to tolerate more noise for a lower price, the Waste King Legend 8000 1 Horsepower Disposer (*Est. $150) will allow you to grind continuously.
