I've been very happy with my Fender Passport 250 and have used it in all sorts of venues. It has always performed well, even outside. It only has four inputs (plus 2 stereo inputs that I have used in a pinch, but you have to do a lot of adjusting). It's very easy to adjust and tweak your sound. For one person, or a duo, it works great. If you need more inputs you can plug in another mixer, which I have done, but just using the basic Fender Passport (250 model) I have successfully managed to get a good sound from a four piece group.
