I have been extremely happy with my Behringer Eurorack MX 602A mixer. I've used it for five years. It is sturdily built, intelligently designed with flexibility in mind, and lives up to its purported "ultra low noise" performance. (For one thing, the pots are well-sealed from any exposure to dust.) I will say, though, that if I were making such a purchase now, I would definitely opt for the eight channel version at a minimum.
