I would also like to hear this. Although that A3 was out of my price range to begin with.
There was a recent FWW article on the less expensive JPs. So they didn't have the A3.
The changeover on the grizzly was 2x as compared with the JET. I am using the JP also as a jointer and still using my lunchbox planer, but that certainly would be a drawback if one wanted to use the tool as intended.
