PCB Prototyping Manufactures

There are many pool or community batch prototyping manufactures that produce excellent result for around $5-$10 a board. This is really a great option if delivery-time is not a concern for you. 

In our development cycle, however, we tend to have very short time-windows available for  prototyping, so this is the main reason it's not always and option for us - , but it may be the perfect solution for others.
