I strongly recommend purchasing a USB bluray player + then buying shiny metal disks to feed it (or finding your public library, of course!)
Used + overstock disks are << $10. I go to the store and grab what I want. I typically leave with about 30 movies / TV seasons for $100. They're far higher quality than the content that is included with amazon prime, and typically cost about 10% as much as the "buy movie" price for the same film.
