I was about to pull the trigger on one of the hifonics zrx 1500.1 or brx 1600.1 for $160/$210 when I came across the scratch and dent refurb SAZ-1200d units for only ~$250. I believe there has been benches where this amp hits ~1700W (and not even at 14.4V). Also, comes with a 1-year manufacturer's warranty, which is also a plus. Has anyone bought one of these and if so, how has it held up?
