I bought the all of them. I hated the grip at first but now I love it. I didn't realize how often a flex head would of saved me a few headaches until I got them. I just wrench on the weekend so the quality is just fine for me.
I put one of them in a bridgeport and drilled the 2"x 2" pilot hole grid pattern so the first one was perfect. From there I matched drilled all of the other ~600 holes with a drill press which took me wayyy longer than I thought it would. The middle row on each plate will work with most...
Here is mine. It's still a work in progress but its getting closer. I designed it around a StrongHand Table.
