I use a cheap MC-30 knock off I bought from Amazon if I remember correctly. I bought 2 at the time for under $25, they look the Remote Shutter Releases Amazon is currently selling made by Digital Concepts. They have the locking 10-pin connector, 3 foot cord, and you can lock the button down if needed. I used them with my F5, and D700 and have never had a problem. I've primarily used one while keeping the other as a backup but haven't had need of a backup yet.
