Yes, as @howard said, he created a whole thread just for these Zoom pedals (see link):
I actually just bought one last week, the B1 Four, this thing kicks ass, I’m still just figuring it out. I tried to find it used, but no luck at a good price, so just went on Amazon and paid retail, about USD $80. Now I need to go back through that thread for all the great suggestions! I got it because of the suggestions on that thread, and the good experience others seem to have had with it.
