Boss do this sort of thing really well. It's small, fairly light, definitely loud enough for most applications and looks pretty slick to boot. You get some handy onboard effects and separate controls for your vocals. It'll do the job nicely for cafes or smaller venues etc. Be careful though, it's a bit Bossy.
