Holy god! Canon says they will take my broken 20D off my hands and give me a brand new 50D for $629, that's $500 off the new price!! MY 20D started Err 99'ing the other day (at a wedding no less), and now, the shutter wont open, but the mirror flies back and forth non stop once a battery is placed in. I'm really, really, REALLY considering Canon's offer. Is the 50D worth it? I thought I might have heard some negative rumors a while back in regards to the noise levels of the 50D.
