This thread got me thinking about the already in-progress process for me to replace my very old, lower end Bluray player with something more Oppo multi-format-like. I ended up getting the Sony 800M2 at Best Buy, think it was $260 plus tax. It's a bit bizarre what formats and disc types it will accept, although it plays most with only certain ones for whatever reason not playing. I had intended to keep my older Oppo dvd player around anyway for random DVDA and SACD playback, so the fact the Sony got me so close to replacing two devices with one is pretty amazing. Also great with the Sony are the dual HDMI outputs on the back, I ran one direct to my 4K TV and the other 'audio only' HDMI to my receiver. My receiver isn't 4K compatible (it's older, and next up for replacement) and wasn't passing the video through, so having the ability to split audio and video was key.
So far so good with the Sony. Tossed every format I could think of last night at it and it played most (quad and one older dvda burn were the only "nopes").
