Due to the nature of this thread, I am guessing what we have on our keyrings are more jingly than other "normal" folks. I just bought this: http://www.blackhawk.com/product_detail.asp?product_id=1610&d= Basically just a strip of nylon with velcro that wraps around your keys and gadgets to keep them silent. It is cheap and effective. Also, it doesn't add too much additional weight and bulk to my present keyring. What do you guys think or what do you guys use?
