On paper, the Panasonic DP-UB820EB looks like quite the prospect. This 4K Blu-ray player borrows much of the picture processing technology that you find in the company's flagship 4K machine, the DP-UB9000, but costs less than half the price. 

The main unit is pretty minimalist in terms of design, with just two buttons on the top panel for power and opening/closing the drawer. The front panel drops down as the drawer extends out, revealing the player’s display (which is also visible with the panel up) and one of the DP-UB820’s two USB inputs. This particular one allows you to play content from a portable hard drive.
