Denon's line of DVD players seem to be the standard by which most others are compared these days.
The DVD-2900 has been universally hailed as a really great player. It plays back pretty much any disc you throw at it. CD, DVD, SACD, DVD-A, as well as all your bootlegged burned cd's and dvd's. Original MSRP was $1000, but you can usually find one for under $600 through Ecost & Dakmart (refurbs) or used on audiogon.com
The
Oppo has been being called a giant killer in the video quality department. (As long as you use the digital outputs (DVI or HDMI). At only $200 you could afford to use the Oppo as your dvd player for it's superior video quality, and still afford a stand alone cd/sacd player for audio.
