The 10 pin cable release is very common. There are a number of different versions from Nikon and third parties.

The third party cable release is probably a good option. It's not as well made as the Nikon release, but is a fraction of the price. I have one and have worn it out.

I also have a Nikon cable release. It's well made and there are no issues.

There are also cable releases that let you control camera settings on the release. This type of release is a good bit more expensive but useful for some types of photography.

Precision Photo is a good source of Nikon accessories and third party alternatives. I keep spare lens and body caps in my camera bag.
