I'm not sure what cheap to you is, but Xbox One S is regularly $200 new with a game. There's the Samsung and Phillips players too that are about the same price. Just depends what you want really.
Hopefully DV players go down in price, or at least come in more options than like 3. Feels a little silly to not buy a DV player when you have a DV TV.
But yeah if you don't watch Blu-Rays regularly, all that investment might not be worth it.
Netflix/Amazon is a good start, but UHD discs are really something else. With the coming price hike to Netflix, I might actually cancel as I feel it's no longer cheap enough to just sub to without watching regularly.
