The single most important thing is to buy models with SS grind components, These cheap models with galvanized grinding components wear very quickly having a large gap around the turntable which allows large items like strips of potato peels to pass through and clog your drains.

These small high RPM models also have small capacity and are not well suited for grinding lots of bones or just large loads of food if you are doing any serious canning or quantity cooking.

We do a lot more service calls on these hi RPM disposers because they are very hard for users to unjam because of the lack of a self-service unjamming  wrench.

When you get into the upper end models nothing comes close to the In-Sink-Erator built disposers, they are quiet fast and longed lived without the cheap to build small hi speed motors and best of all ISE disposers are built in the US.

Well, I don't care to put bones down the disposer. Instead they go in a resealable plastic bag in the freezer for making bone broth. Any bones left either go in the trash or the compost pile.

The Joneca/Titan/American Standard garbage disposers are high speed, but the also have all stainless grinding components. To keep them clean I occasionally put a handful of orange peels down them. Works for me!
