I can understand your confusion, as that's a tough bind to be in. However, my immediate response would be to wait.
I'm not sure why you dislike Panasonic, as I think they make very fine products, anything from plasmas, projectors, dvd players, cordless telephones, fax machines, irons, etc.
With the above in mind, my friend found some Panny DVD players on fleabay for $20 apiece, new. He bought four, gave one to GF, parents, etc. Works perfectly fine. You can do that, and save up.
IMO, you will want to upgrade display before player. I'd go cheap on the player during the meanwhile, JMO. Think of the display as the choice in speaker, and the dvd player as the choice in cdp... sorta.
I want to add that my preliminary research and excitement over bluray was with the audio improvements. I'm here to tell you that the video improvements are vastly greater than the audio ones, IMO.
Save up for a new display for the day that your tv croaks is what I say. JMO, if money is a serious issue. If money is no object, of course you can just buy new everything immediately.

However, this does not appear to be the case.
edit: you are right AVRat, the manual does not appear to be available! (strange).
