Is a Denon DVD-5000 worth buying ?

I have a chance to purchase this top-end in '99 player for under $400. I noticed there are a couple on A'gon that are not moving ( they are more expensive ). I'm just wondering if a top of the line unit in 1999 is really that obsolete to not warrant a reasonable resale price. I suspect the lack of progressive scan is turning off perspective buyers but wouldn't a high quality non-progressive put out a better picture than a cheap progressive ?

Comments on this units ability as a CD player also appreciated.

thanks everyone.
