If you check at harmonicdiscord in the modwright forum, you will see people seem to like the new Pioneer Elite DV-45A universal player (CD, DVD, SACD, DVD-A, and mp3, I think,) which goes online for around 420.00 to 480.00.

For 500.00 you will get progressive scan, so you sort of don't have to worry about it.
The only other consideration might be, since your HT is a few years ago, to get a sub 200.00 DVD player until then. Technology will advance. At this price, you could get a decent Pioneer without SACD, or a Sony with SACD that some people say would not have as good a construction quality as an equivalent Pioneer.
