A number of members here use the BrickWall PW8R15AUD ($279) and have reported excellent results in terms of sonics. And the writeups and specs for it you'll see at their site on that and other pages (such as this one) seem technically sound and are confidence-inspiring with respect to protection.
I too used one for many years a while back, with fine results. Eventually I changed to something more expensive while I was making other changes to my system, but that change was not due to any dissatisfaction with the BrickWall.
Good luck. Regards,
