I also use them for display and paint work.
I found some cheap IKEA floor lamps that I attach a Panavice head to, and display models.
They have a weighted base and are very stable. They have removable sections, so that the height of the model may be varied.
I’ll try to find the item number for the lamps.
In the pic below, the studio scale x-wings in primer are displayed on those ikea stands.
