I'm about to build a system for a friend who is trying to spend as little as possible but still wants the system to sound "good." He doesn't have a budget in mind, but wanted to get an idea of what an acceptable system would cost. I wanted to get other people's thoughts on the cheapest system that they would find acceptable/decent for home theater. For now, let's not consider used prices, only new components for a 5.1 system. What components would you pick for your cheap/decent system?
