From Amazon "The HEYMIX Aluminum single monitor stand fits most screens 13" to 32" in size and 1.5kg to 9kg in weight with quick Release joint installation with VESA plate 75x75mm or 100x100mm mounting holes. 2-Ways mounts to the back of your desk (10mm - 80mm ) via a heavy-duty C-clamp or optional grommet mount (10mm -60mm)."
I bought one of these in a recent deal for around $40. They are really solid, delivery was within days so it's AU stock, and I've had no issues. I reached out to the seller for a deal as I needed more, they were super responsive and now I have 3.
Based on previous oZbargain deals, it looks like this is a historical low for Boxing Day.
