I searched your posts to see what your display was. Yes, I'd also opt for the best upconversion with a PJ (if you can still watch DVD on FP, because I can't).
Oppo uses Anchor Bay. ABT >> Faroudja.
As always, it all depends on how much it's worth it to you. For the very best, you'd want an outboard video processor, but no, I don't think it's worth spending more on that than you did for the PJ.
Get the Oppo, unless any of the Denons you are considering have good stuff onboard, like Realta, but that means you will be spending even more in all likelihood.
