I can get you a brand new FSD 1600 or 2600 well under that price, they're Zenon boards which are where old sundown amps were made, same as the encore crescendos too. Shoot me a PM for details
My price actually isn't bad considering it's never seen power, but if if he decides to go with FSD then cool. As long as he finds what he's looking for, that's all that matters.
