Shure donuts look nice...but I can tell you that without a doubt the meeks that you linked work also. I used them without incident. I still have the Meeks and use a single Meek as the mount for my Neumann active setup and I really like it's isolating abilities. The bands are a bit springy so that I knwo there won't be any sound transmission through the mount.
One semi neg comment about the Meeks is that with the springy bands, if you have cables that aren't very pliable, they can tug a bit on the back of the 480s, which of course are rather long mic bodies so they jut out the back of the mount a ways. If your cables aren't hanging very freely, they can tug at the back of the mic bodies and cause some sagging, since the mount isn't a real tight banded mount.
If I were to do it all over again, I'd probably go with the donuts as long as people could assure me that there is good sound isolution from bumps through the rubber donut in the mount. I know that there are lots of satisfied users with these.
