Waste King Garbage Disposal 8000

I don't know that much about waste disposers. My Plumber told me to just look for a disposer that was 3/4 horse power or better with stainless inners. My old disposer was a cheap one installed by the builder and the inners were not stainless. It rusted until the blades would not turn. I went to Consumer Reports to determine which disposer to purchase.
The Waste King Garbage Disposal 8000 Lengend Series 1 HP Continuous Feed Operation Waste Disposer was the one recommened by Consumer Reports. Buying this disposer on Amazon.com, I believe saved me about half (the disposer plus shipping without tax) of what I could do elsewhere. It arrived quickly and in the original sealed box. My plumber just installed the garbage disposer, so I haven't used it. But, I have had it on and it is fairly quite. He indicated he had read the Consumer Reports article and agreed that it was a good disposer. However, he did indicate you could get better commercial grade disposers at places like Lowes. However, he also stated that it would cost at least twice as much.
