The controllers are like if you split a regular console controller in half, that and considering how much smaller they are and how fewer buttons they have, they should halve the price tag and save the $50 price tag for the pro controllers and such since those are whole controllers
Considering you can buy the left and right controllers separately, and how much less they have compared to a real console controller, you shouldn't have to pay more for less, even if the controllers are $10 cheaper than most controllers, for what you're getting, if you only get one or the other, $50, to me at least, is a bit much
