I've had several Mackies in the past--a 1604,and a couple of 1202s. They are good mixers and were innovative when introduced, but I think they are a little overrated.
My Behringer 1222FX Pro, at about 1/3 the price, runs circles around the Mackies I've had. More features, lower prices. Reliability?? We'll see, but so far it seems to be rock-solid.
