I'm making one that will be put away under a work table. It rotates to allow the planer to hang upside down. It's a Dewalt 735.
I'm debating about the casters. Ones that lock are expensive and not so sure I don't want to use only two anyway and have the others as fixed legs.
I only have to move it 10 feet so distance is not an issue. I'm still at a point I can tolerate different wheel size.
My thoughts are the small and expensive ones that take about 2" of height. Those don't lock.
