Check out the review section on this site for a review of the 50A556 (same set). No review of the PZ80, but the PZ81 and PZ85 have been reviewed. These are all similar PQ. just different bells and whistles.
I would go for the Pany , just about to buy myself if the builders would just finish completely. But you must just look at both as only your eyes can descide which is best.
