If I didn't have one, I'd want one. That is just how it is with us tool guys. I have at least one, but I can't ever remember using it. Maybe if I would have had it when I was a teenager, I would have used it quite a bit, who knows?
I also don't like air ratchets, as they were not available to me when I was growing up, so I got used to doing everything by hand. I like the feedback that you get from hand tools. I remember spending more than one day trying to remove one of those big Chrysler crankshaft bolts without an impact wrench because an impact wrench was just a fantasy to me. Not something that I could actually OWN (or even borrow from a friend, because they didn't have one either). Boy, have times changed.
On the plus side, I am putting together an engine for my truck, so I will try to remember to whip out the speed handle for things like the oil pan bolts and such.
