Mozart's Requiem- Best recording on CD

I'm looking for an excellant recording of Mozart's Requiem on CD. There are tons of available, but which ones are recorded well? Any recommendations?
I too sing in a choir (a good church choir), and I agree with Sugarbrie as to the Scheier performance. Sound is pretty good, and the soloists are top notch. The Boston one that he refers to in his latest is, I think, the Pearlman/Boston Baroque (sp, I'm sure) on Telarc, which I have not heard. It undoubtedly will have good sound, judging by their other discs, which I have, but I've not heard the version they sing. If I'm right on the ensemble, the choir will be smaller than you might otherwise be used to as well (I have their Bach Mass in B Minor).
Yes, that is it. The Perlman/Boston Baroque for the Robert Levin version. I've sung the whole Levin version in Baltimore for a Music Scholar Conference with Levin in attendance. We also sung parts from the other versions for comparison. Fun Day !!!!
Sugarbrie, that does sound like fun. Any preference as to Levin's version vs. the Sussmayr? Given Telarc's virtues with their other Boston Baroque recordings, it might be worthwhile to pick up, if only for the comparison. Also, I might want our choir director to give it a listen.
Yes give it a go. I have three recordings: Boston Baroque/Levin, and the Scheier on CD, and the old 1967 standard with Colin Davis and the BBC Symphony & Chorus on LP. I listen to all for a change of pace, but the Scheier the most. I gave away the Hogwood/Maunder a long time ago. One listen and out. If you perform the Levin, do not be afraid to contact Robert, maybe he will come and give a talk, who knows.
Thanks to everyone who responded! I've already started to obtain some of the recordings. In my experience well-recorded classical CDs are difficult to find. Thanks again!
