The professionally priced stuff is from Rycote. They have several different solutions, the best known is probably their Zeppelin (Full windshield system). If you use the cage, the undercoat and the dead cat fur your mics are really protected (ie, overdoing it for most of us).
http://www.rycote.com/search/index.phpThe web page is, well, not the one I love most in the world, but the products are what the pros use.
I believe you have to look at CK1 460 as the 480 is not listed.
As a side note, their InVision Suspensions are well worth to look at, quite less expensive than I expected....
