Hey, I've owned the first gen MB115 for nearly three years. Haven't really fallen in love with it. Horn hisses too loudly to use. Not enough volume for rock/jazz with drums. Mine just left on a warranty trip from Fla to NYC because it quit working. That said, if you can pick up a used MB115 for about $200, you may limit your future unhappiness. There seems to be very little real difference between the two. Be sure to check out the horn hissing issue before buying.
