The plumbers like Insinkerator.
They also make them under some other nametags too.
I notice that the PRO that the plumbers carry has some parts that the big box disposers don't have, and the in-home warranties tend to be a year longer.
I don't care fro WasteKing. They tend to run them at too high a speed, and I don't like the sink connection that they come with.
