I own the HD8300, known as HD83 in europe. Well, i just use if for 3D as I have an RS45 for 2D aswell and an old Sanyo FullHD for tv viewing.
Besides that ,the HD83 does excellent with 2D material. Good native contrast for DLP, very much pop and superb sharpness. No RBE visible - which for me was a big deal as with every other DLP I used i was sensitive to RBE.
At it's price point the HD83 is a winner both in 2D and 3D.
Not to forget the very good lens shift range for a DLP.
