I agree that threader is great.
I found another item by accident and love it, so I appreciate the feeling:

I love it for doing binding. I can have 10 needles all threaded and ready to go. I did have trouble locating more after my first one, but this way I can be ready to do binding for either a large quilt (I have been doing more queens and kings lately) or more than one quilt.
