Yeah - the older models deinitely only have PLII - I think PLIIx only came out commercially in October or November of 2003.
Some of the retailers online definitely only have the PLII models, whcih is probably one reason why the model is going for sale on line.
I also advise a quick call to your online e-tailer to make sure that the box says "PLIIx" on the outside. Ask them to read the box before telling them what it means or asking them if it has it.
If the Denon has the same up-conversion feature (I saw that it does have component video switching), then, you are probably right that it is a wash - But I think I'd be willing to pay a little extra so that my rear channel investment gets a work out too.
