The first two links in this thread point to stand adapters that don't isolate the cable from the stand. That defeats much of the purpose of having a shock mount. I give those items a hearty "boo" (unfortunately this applies also to the otherwise very appealing Shure rubber donuts).
--Are people here aware that the sensitivity of a microphone to solid-borne noise and vibration is a function of the capsule type? Since Schoeps mikes are all single-diaphragm, you can relate this directly to directional pattern, with omni capsules being about 20 dB less sensitive than figure-8s, just as they are less sensitive to wind and (for close miking of speech and vocals) breath noise and popping on consonants. If you have MK 5 or MK 6 switchable-pattern capsules, the sensitivity to solid-borne noise corresponds to the pattern setting.
That all said (sigh), Schoeps has a long tradition of manufacturing their own mounting accessories, as well as accessories for other manufacturers--for example I have some older "Neumann" wind screens and desk stands that were made for them by Schoeps, odd though that may seem today. They also offer thin, lightweight microphone cables with Kevlar-clad insulation that are terminated with Neutrik EMC connectors--the kind that stops most RFI problems dead in their tracks. Those should be used by more people who do location recording. And I've always used their stand adapters, which I like especially now that they're using rubber instead of hard plastic for the parts that actually contact the microphone body.
These accessories end up with price tags to match, however. Schoeps has a significant number of customers who prefer to buy Schoeps accessories for their Schoeps microphones, so it makes sense from the company's perspective to keep manufacturing these items.
But (have I buried my lead enough?) as far as shock mounts are concerned, I find that Rycote has solved the basic engineering problem in a way that others have not. Their InVision shock mounts are distinctly more effective at doing what a shock mount exists to do, than any other type I've seen in 40+ years of recording. My only complaint is that when I use one to hold a stereo bar with two cables coming off of it, it's a little hard to get both cables fastened reliably. But as far as the suspension itself is concerned, as long as you're using the right type for the size and weight of microphone(s) that you're suspending, they're miles ahead of anything else around.

P.S.: Any time John Willett and I agree 100% about something, y'all might want to pay close attention.
