That machine is actually a Star Rifle Machine in 223. Star did make a machine referred to as the Star 223 Pistol Machine that for lack of a better description is a Hybrid between the Rifle Machine and a Universal. The Rifle Machine has a 1" taller column, and a large capacity powder slide. The rifle machine uses a tool head with a thicker flange, that is not compatible with a Universal. Most have an adjustable powder slide, but I have seen early machines with brass powder slides.
The 223 pistol machine has a standard Universal length column, uses a Rifle tool head and has a thinner powder slide that uses bushings. I have only seen one 223 Pistol Machine in the wild, so I would say it is even more rare than the elusive Rifle Machine.
At $1500, the machine on eBay is priced fairly. It is missing dies, but standard RCBS 7/8" dies fit and work well in a Rifle machine. I can't see if it has the Star expander, but not really needed if you use a sizing die with a carbide expander ball. If I didn't already have a couple of them, I would grab it.
