Ernie Ball B guitar...?

I want to get an Ernie Ball Musicman b (first b), but I don't know which model to get. I've only heard the Bongo before, and it sounded pretty good. Please tell me the cost of one, (I have a small budget, I don't think I can get one under $1000) and what a piezo is. (I think it's just another knob, idk?) IF YOU HAVE SUGGESTIONS FOR A DIFFERENT B, PLEASE SAY SO, BUT NOT RUDELY! I will be playing Primus, Pixies, Replacements, AC/DC, Dinosaur Jr., a little bit of Green Day, Iggy Pop, Mission of Burma, Minutemen, Minor Threat, Velvet Underground, RHCP, etc.
