I've had excellent results with a Fishman Solo Artist. I wish the build quality was a bit better but it sounds excellent and is loud enough for me, my acoustic and/or electric guitar, vocals and backing tracks to be heard indoors or out for up to 100 people. I just used it direct on a video shoot and the video guys agreed it sounded excellent. It's under 30 lbs. and gets used much more often than my Turbosound IP-2000.
