I'm using a Mede8er MED600X3D. I love it. It's XBMC based with a large community of modders. I stream uncompressed blu ray mkvs with lossless audio from my NAS without any problems at all. Supports HDMI 1.4a, 3D, and pretty much everything I throw at it. The only glitch I've had is that it's not licensed for DiVX on AVI, so I had to change the FourCC to XVid, and that solved it. AVI is dead to me anyway.
It doesn't fulfill the netflix requirement, but after many years of playing "find the magic codec" with my WD devices this one was simply an awesome breath of fresh air.
