Puster Bill,
Maybe this is a good place to ask. I have read 2 threads on these tools, and still I don't really get what function they perform at what convenience! Its a catch22 for me, I have a hard time understanding exactly what they do, and how easily without having the wiz wheel in front of me going along with the thread.
Do you really gain a good bit of time back using one, and do they get rid of all the little 2-boat triangle note pad drawings next to my desk

? If so, I think I may actually build one.
