Thinking about upgrading my blu ray

Just starting to think about upgrading my old Pioneer BDP450 (multi region dvd/region B BR)

it has served me well and i use it for SACD play as well

I have always had half an eye on the Oppo range but keep thinking that approx $1000 is a bit steep for my set up

Here is my set up. What are peoples suggestions for a new BDP

Marantz SR5007

B&W Series 2 fronts and rears

B&W ASW sub

BENQ projector and 120" screen

mainly for movie use, some CD playing and SACD

Multi region DVD capability would be useful but not essential

Dont really see a need now for multi region BR

thoughts ??

my budget would be $500 ish
