Yeah, it seems that for the performance and price the Oppo is the unit that has it all right now. I do like the build of the Denon's but given the price the only BR player I would get from them at the moment really would be the 2500BTCI ($299 shipped on Amazon at the moment)...
I love my 3910, it's built like a tank and I think it has marvelous audio quality when it comes to CD listening....it does a good enough job upconverting DVDs...what it doesn't do my Pioneer display takes care of....
