Depends on your definition of "quite pricey." There's no equivalent of a $250 50" Insignia FireTV, but I've seen Samsung signage displays on Amazon for about a $75-$100 premium over their comparable Smart TVs. They also don't come with a stand, so if you weren't already buying a VESA mount you'll need to add another $40-80. There is a significant premium, but it's not necessarily orders of magnitude.

And they're made better… To be on 24x7. So you're also paying for a better quality display. That's worth paying for too.
