As far as I am aware, the newer versions of the Jacobs super chucks are made in China, most of the reviews have been disappointing. I would not recommend a new one, and finding a NOS or one in decent condition can be pricey. I would recommend looking at the Llambrich chucks which are made in Spain, I have a few of their integrated arbor chucks and very satisfied with them. The CBB-16 (5/8'' x JT3) is a ball bearing keyed chuck that I would look at. Vertex makes some decent ball bearing chucks that are less expensive. Some of these come up on Amazon, as well as other tooling at very low prices, example below. I would recommend the Llambrich if you can get it at a reasonable price.
