Hey Becky, You must be a bottom feeder. As a top feeder, I love that the upper arm doesn't stay up! I let gravity lower the blade into the hole, instead of having to pull the upper arm down.
I used to have a Jim Dandy on my saw years ago. I took it off because it was just in the way.
I don't mean any disrespect by calling you a bottom feeder. It's like being left handed or right handed. You are either a top feeder, or a bottom feeder.
BTW, I'm am left handed!
