Definately get yourself a good BR player. As Trevor noted, the panny's are good and not expensive. Streaming is convenient, but sound / video quality can't really compete with a nicely mastered 4K BR.
I have simular feelings about buying CD's, verse downloaded MP3's. Sometimes I hear a song I like, then try to find the CD. It does not exist, only thing I can get is a download. Every friggin time, sofar, the download sucks. Amazon is getting horrible about this. Seems they make more money selling you downloads, so you can't find the CD's or BluRays.
