I know this isn't an original idea. In fact, I think at least one manufacturer was selling a kit of this sort a while back. This is my first try at this sort of thing and it seems really useful to me. I'm wondering if there's anything I could have done to make it better. I built this one for a friend and plan to make one for myself soon.
