I do not agree with the insignias recommendation. They are not very good. I'm using them with a T-amp for computer speakers. Yes, they are cheap (I paid $40/pair), and for the price there isn't much to compare them with. But they are way over-hyped, IMO. I heard the A/R speakers for $100/pair at J&R, and thought they were a lot better than the insignias - build quality, components and sound. Of course, it's hard to judge very accurately the way J&R has things set up.
The T-Amp, on the other hand, is quite good and a bargain when available. IMO, it's worthy of the hype.
