I have a Passport 150 for situations where its crucial to be small size, light, compact. In my humble opinion Passport should be a choice ONLY IF your top priority is portability, as the sound quality has limitations. The 150 model (two channels, 75 W each) is very very light (10 Kg) and everything packs together in a box of the size of a big suitcase. There is a mixer with a basic equalizer, reberb, 4 channels, comes also with a (low quality) mic. I heard that, in the same kind of equipment, Peavey makes a better quality package slightly more expensive: Peavy Escort. These sound systems are ideal for lonely travellers, that do "busking" (playing in the streets): you can operate them with a 12V battery as a power source.
I like it very much for very specific situations, but I would never take it to a club or a party. Not enough power, and limited sound quality (the speakers are too small, weak low end). There is a more powerful (and heavier) system, Passport 250. But if extreme compacity and very low weight is not your top priority, I concur with Donny: there are much better choices out there.
