May tag is definitely on my radar, as are Viking, National, Kitchenaid, an older Waste King, and InSinkErator. There's an ISE Kenmore I'm eyeing, hopefully in a week or so it'll still be available, I may g for it, but it is on the newer end of what I'd like to find (I think early 90s, could be older), but its the sort of disposal I'd like. I do like the idea of the fixed hammers, it seems merciless and effective! Also I'd imagine the fixed hammers do well with things like beef bones...
I don't have this video on YouTube, but I got a video of pro ribs and watermelon rind getting disposed of, Tim's brother in law stopped by the night I installed this, and we had some fun. At the end of the video we ran some rind chunks dow it with the splash guard out. Comparing the action to what you see when doing the same in an Anaheim unit was something... This is where I came up with how it seems to work. The rind pieced would tumble over to the spike, stick there for a moment as the impellers chopped at it, it would quickly break up and off the spike and the smaller chunks would sort of slowly swirl above the whirling impellers as they literally would just fade to nothing. This whole process is over faster than you can snap your fingers twice. In the Anaheim WK's I've seen, the hammers usually are pulverizing the chunks against the grind ring, but this GE seems to largely do the job against nothing but a smooth stainless steel wall, relying on the speed of the impellers and whatever keeps the food chunks moving slower than the flywheel, they literally just kind of mozy around the grind chamber wall as the thing chews on them!
