For a "high-end" "non-progressive scan" DVD Player available for under $1K, then I would look at the following players (all of them are discontinued and you will probably end up finding all of them on the used market):
(01). Pioneer Elite DV-09 (about $700.00 to $950.00 used)
(02). Sony DVP-S7000/DVP-S7700 (about $400.00 to $650.00 used)
(03). Denon DVD 3000/5000 (about $500.00 to $700.00 used)
(04). Nakamichi DVD-10s (about $800.00 new)
These are the only ones that I can think of right now, and the ones I would look at before I would look at a brand new DVD Player that lists for about $200.00 or less (build quality isn't there).
Also, if you don't mind getting a "progressive scan" player in spite of your desire not to, then another great player to look at is the Toshiba SD-9100. It was Toshiba's flagship DVD Player last year. It listed for about $2,000.00 when it was brand new. You should be able to snip up a used one for around $600.00 or so. But I wouldn't pay no more than $800.00 for it. Anything above $800.00, then you might as well start looking at a new one.
Hope this turns out to be helpful.
Good Luck,
