I'm looking for a portable stereo PA setup, somewhere in the $500 
range. I want to run a guitar (through a multi-effects processor), 
sampler, and drum machine, all with stereo outputs. I'm considering 
the Behringer PMX 2000 with a couple of 12 inch cabinets, the Fender 
passport P-250 system, the Soundtech AL2R system, or possibly just a 
couple of powered speaker cabinets, such as GEMSOUND MA1200. Does 
anybody have any experience with this equipment, or any other 
suggestions? I basically just want a stereo setup with good sound 
quality and range (especially for guitar and sampled sounds), loud 
enough to play small shows by myself or to play along with a semi-
loud drum, bass, guitar, ensemble. Thanks!
