I'm currently not desperate and I want to keep these together.
I do have an extra grip that has a faulty shutter release, though, if you're interested. Basically, the thin rod at the end doesn't extend far enough out and will not depress the shutter. You can try to fix it, or, since it's the version of the grip where the shutter release cable is detachable (I believe these are later model grips), you can look for a replacement cable. Alternatively, you can velcro tape a different cable onto the grip like I was doing till I got a replacement grip
Let me know if you're interested in that. $25 plus shipping & PP.
