I haven’t voted yet but based on the info you’ve provided I’d go “large w/ BD player” based on your seating distance.

A few other questions:

Do need the multi-format capability of the Oppo?

Do you need something that can stream Netflix?

Is the ability to play 3D Blu-ray content important to you?

How long do you need each component to satisfy you before upgrading especially the screen?
