what is a good garbage disposal for stainless steel sinks?

Heard that stainless steel sinks cannot sustain heavy garbage disposals and may make the disposal more noisy. I am considering either a InSinkErator Evolution Compact which is listed at 20 pounds or a WasteKing L3300 that is spec at 12.4 pounds. Both are 3/4 HP which is fine for our needs. I'm wondering if the sink can withstand the 20 pound InSinkErator weight. Sink is 16 gauge thick. Any experiences on mounting and noise considerations?

my bone crusher died recently, it lived its life on my low end stanless sink, not knowing what it weighs, i installed it over 15 years ago..
weight never appeared to be a issue, although it was noisey

I have a big Kitchen Aid in my SS sink. No problem with weight or noise. ISE is made by the same parent company and is a good brand also. No experience with Waste King. Most disposals have easy mount systems too so installation is not a big deal

yeah the only real concern with a SS sink, unless it's really flimsy (16 gauge should be OK, I'd think) is noise, as the SS will tend to amplify any noise from the disposer. If you've got a good sink with a resonance damping coating this will help. If you just have a bare SS sink I would put something on it to quiet it down, look to your local mobile stereo installer for products, there are brush/spray on products like Lizard Skin and also stick on products like Dynamat. Apply to underside of sink bowl. This is a good way to make an inexpensive sink sound like a more expensive upscale sink. Also when picking a disposal there is a difference in sound levels between models, read the labels/specs to pick what you think will be good for you.
If you're replacing an existing disposer, if you buy one of the more "upscale" quiet disposers it will undoubtedly be quieter than whatever the builder put in.
I just replaced a disposer a few weeks ago in a townhouse that's about 30 years old, with presumably the original SS sink. I didn't see any issues other than that the 30 year old disposer had finally failed (shaft seal had failed allowing water to run through the motor and eventually the water started dripping on the cabinet floor and the disposer's bearings locked up.) New disposer is working fine in original SS sink. I used a ISE "Badger" 3/4hp model, not the least expensive model but pretty close to it (I didn't want to put in a disposer with a lower HP rating than the original, but I was doing it for a tenant as her landlord was unavailable at the time, and didn't want to cause tension by getting too fancy a model either) and it's not particularly quiet, but sounds just like every other disposer out there pretty much.
I like using ISE because they're very common and I like their mounting setup where you can remove the whole disposer with a hammer, screwdriver, and pair of slip joint pliers, plus if the thing fails again for whatever reason it's likely that an ISE replacement will go right on the mounting flange saving time (the one I replaced I don't remember the brand - GE maybe? - but it had a different mounting arrangement, so I had to remove the old mount from the sink and use the new one that came with the new disposer. Not the end of the world, but it made the job take a little more time.)

After 20 years I had to replace ISE one with direct replacement newer SS one 3/4 HP. Dual SS sink has sound deadening foam spray coated underneath. I did not have to remove mounting hardware, untwist, drop old one, after moving wire to the new one, twist and install. Done in less than an hour. I called ISE customer support in the middle of night a woman answered right away, when I asked direct replacement current model giving my model no. of old one she ave ganswers right away. What a service talking to warm body w/o waiting.

I have experience with both Insinkerator and WasteKing. The Insinkerator mid-range and better are quieter. There isn't as much difference when running and actually processing food as there is at start-up, especially if the WasteKing is totally empty. It makes a clang/bang kind of noise when it first spins up, probably the blades rotating out. It was worst when it was new and had nothing at all in it. When I first heard it I was surprised how loud it was. But after using it a bit, I think some food residue or something helps keep the sound down, as it gets quieter. I still don't think it's as quiet as the Insinkerator, but then the Insink I'm comparing is in a cast iron sink and the WK is in stainless, so it's not exactly fair either. The difference in noise doesn't bother me, but then I only use it maybe once every other day. It's still an excellent deal at half the price of the similar Insinkerator. WK also has either a long or lifetime in home service warranty if it craps out and it's made in America. But if noise is major concern and you're willing to pay 2X the price, then I'd go with the Insinkerator.
