This is my new magnetic base for indicators, and I am finding it to be very useful.

It is just the right size for use on MiniLathe and MiniMill and has plenty of articulation. All the joints tighten when you twist one knob. It is readily available at the big auction site.

It even clamps to the quill on my mill.

Here I am using it to center a rotary table.

I had earlier bought this larger magnetic base, but found it to have too little articulation to be of any use.
