Y'know, for almost twice the price I just can't see how the Yamaha is almost twice the mixer...
Behringer gear gets a bad rap around here but I've used a 3216 recently and was impressed with the lack of learning curve and good sound. You're never going to have a studio that sounds like it costs a million dollars unless you have a million dollars to spend on it, so you might as well get what you can afford.
IMHO.
