In the last band I was with, our guitarist had a couple Kustom PA speakers that sounded quite nice, and they were quite affordable. At any rate, they were a huge upgrade over the old 1970's Peavey towers he had that had a couple blown speakers in them. Drove the Kustoms with a basic Peavey mixer amp, and they were very clear.
If things end up going south with my current band, I am thinking of doing my own project (maybe...) and if I do, I might get a Kustom PA setup for my garage. Musician's Friend has some good deals on their stuff right now.
