How do I make or get a 3D printer extruder?

I have NO clue where to get myself an extruder for my printer. Can anyone tell me? I'm hoping I can get it from a place in my city. What sort of shop would I look for?

I've never ever seen one in a store. I'm buiding a Hadron ORD bot, and I'm using a Makerbot Stepstruder Mk7. Fact is, unless you live near a machine shop that makes them (unlikely), you have to just bite the bullet and buy online.
