Kain,
The Sony 9000ES is an awesome machine. It was my first choice. But it has some problems. It has the "Chroma bug" (so does the Toshiba). It also has limited format abilities (no cd-rw, mp3, DVD-RW, etc). It does, however, have outstanding SACD playback.
Further research let me discover that several high end DVD players, including the $8000 Camelot, use Panasonic transports and decoders! I spent many hours on the internet and more hours in various stores. I finally settled on the Panasonic DVD-A7. (It doesn't have the chroma bug). The Sony DVD-NS700P is also way cool, but the DVD-A7 plays DVD-audio and has really cool blue lights. I was also able to pick one up on Ebay for $350. ($999 list).
I have not seen the Toshiba you mentioned, but I have spent many hours watching the Sony at my friend Mike's house, and I honestly prefer my Panasonic. The picture is better and more stable. That could be due, however, to a difference in TV's. (His is a Pioneer Elite projection unit, mine is a Panasonic direct-view HDTV).
Anyway, I highly recommend the site mentioned in oogins' post. It's highly informative. Then make up your mind.
Good luck!
