Hardware continuous controller

I need to buy a hardware continuous controller. I have seen one used in multiple of your videos but I had not caught the brand name. What continuous controller are you using, and where can I buy one?

For instance this recent video: https://thecrowhillcompany.com/using-controller-with-our-plugins/

Or do other people have other recommendations? I also found these: https://themidimaker.com

Hi John,
