Yep, all great advise so far. I'd say go with the DAC due to flexibility. Buy it from somewhere you can return it if you don't like what it does to the sound of your CDP or you don't think it's worth the money (for the change in sound).
If you really don't care about flexibility and you just want a change (I'm with Les that it won't necessarily be an improvement) then I'd also add the Musical Fidelity A5.5 CDP. There's a great review of it up on 6 Moons.
Me? I'm waiting for the release of the new Oppo BDP-983. I'm going to get it modded (like my current Sony CDP) and retire the Sony from daily SACD duties.
