«  reliable, robust and cheap »

I have 8 years and still use each service. I love the built-in microphone that allows for autonomous and precise enough effect, robustness, reliability and low maintenance cost. I do not like black sheath that leaves apparent son after a few years of service. The price / quality ratio is very good, since it has a sufficiently powerful surround effect (250W) for the price, and seen from the time that I have I'm amortized. With experience I will ever be the same purchase to first gear. But I'd like to change the scanner instead.
