We went with the Sharp. It seemed like a great set in all the reviews plus it is pretty (and lighter!). We absolutely HAVE to have an all-region player at this point (too many other region DVDs in our collection). So we got the Oppo. At some point, maybe we will get a gaming piece with blu-ray or an additional players, but we don't have any "fancy" DVDs in our large collection.
I have to spend some time looking at the accessories you've linked to. (Or get Chris to do it

).
Sadly, the set won't be here for NYE so it's the old giant box for one last year of movie watching.
Now, on to Verizon for FIOS and perhaps their HDTV options (and maybe even cell service at the same time!)
