Actually worth the cost?

I recently upgraded from a Nikon D100 to a D700 and was shocked to see that my fancy new camera does not accept a mechanical shutter release. I do a lot of close-up and long exposure work, so I consider a shutter release very important. I tried to get by on the cheap with a $10 third party substitute for the Nikon MC30, but it fell apart after only a couple of days of light shooting. So, with gritted teeth, I parted with $60 for this model. It is heavy duty, with a solid feel and sure action. This baby is the way to go if you need one. Is it actually worth the cost? For $60 there really should be more to it, like an interval timer or LED flashlight. However, it is a simple, heavy duty mechanical swith, no batteries required, that should last a lifetime.
