Wacom is a big name brand. You can get pen displays from brands like XP Pen and Huion for not much more (https://www.amazon.com/XP-PEN-Artist12-Battery-Free-Multi-Function-Sensitivity/dp/B07GNK18VJ https://www.amazon.com/XP-PEN-Artist12-Battery-Free-Multi-Fu...). And they are true second displays. If all you want is a pen tablet then those are much less expensive.
