Hello Scott,
I've been using the Bose system since Dec. '03 with good results. The only significant weight is the Base/Amp at 35 lbs. You should be able to set up in 15-20 mins including sound check. Base/amp out of the bag and put it in position, set in the bottom of the tower set then the top of the tower, position the bass bin. Connect bass bin and instruments - sound check. Since I also do vocals and use the midi accordion acousticly as well as a keyboard, I need effects so I use a mini mixer with effects rather than the Bose remote. I have a mini van and it packs very easily.
Ciao,
Jerry
