I loved my 2200. It was a quality player. Not a spectacular redbook player, but not bad at all (I didn't use it for redbook in general). Having both formats means you don't have to worry which one a title gets released on... There are also more titles on SACD than DVD-A by far. However, I have a buddy who has the 540D and uses it exclusively for music (redbook CDs and DVD-A) because he says it is an excellent music player. I have heard the 640C and I though it was a very good player. I don't know if it matters to you or not, but I believe the 540D is also region free.
