I got my hifonics bxi2010 for 150 here. It was an impulse buy needed an amp bad. Feel bad for the kid that had it though, paid like 300 for it new and never took it out of the box. The plastic wrap was still on it.
Great amp, great price. Stable down to .5 ohm with good electrical. I bought this monster for a friend of mine's build. Great amp. $200 is a steal. If you don't buy it, let me know and I'll buy it. I have no application for it, but worth it to keep around.
