I have both the Oppo BDP-80 and Sony 60GB PS3 that support SACD.
If you do not intent to use the analog out of the Oppo, The BDP-80 would be a very good player. And the PS3 is pretty fast as well and the HDMI handshake issue from the PS3 are lesser with my Marantz SR6003. Only thing that is the PS3 does not do bit streaming of HD-Audio.
PS3 bitstreams with newer updates. That's actually one pro that no other player can claim. The processor is so powerful that they can probably do whatever is required via software. Sort of future proofs the unit. Older units however (40GB one, for example) had some fan noise issues. More than likely, it's because the CPU heat sink separated from the CPU. So be careful if you're shopping around for an older PS3.
