I just ordered a 983 for it's list price of $400. Maybe crazy, we'll see. They are back ordered so should hold their value for a while. I got in the queue some weeks ago but that was before the reviews hit. Reviews for the 983 are spectacular.
My plan is to use 983 for upconverting SD DVD's, but to compare that upconversion over time to whatever BluRay player I have. Like Cytocycle mentioned, current BluRay players that are reasonably priced are said, by reviewers, to be not as good at upconverting SD as some of the dedicated SD players.
If I find over time that the BluRay player does as good a job at upconverting as the Oppo 983, then, it becomes a tougher call about keeping the Oppo at that point. The Oppo does have SACD, DVD Audio, etc and is said to be rather good at music via it's analogue outs, and I think it's a good looker too...... So if it's got a used value at that point of say $200, might be worth keeping anyway. we shall see.

ps: I'm holding off on BluRay for a bit, until I see how the v2 issue unfolds. Probably will get a PS3 or Panasonic in a few months.
