One of my first mz's was a cva optima. It was a good, servicable rifle. I took several different animals with it before selling it last Spring. I currently shoot a Knight KRB and love it. Though the CVA is a good rifle,I believe the overall quality is better with companies such as Knight and T/C.
The best prices I've seen, so far, on the KRB have been at natchez shooters supply:
