From Arduino and breadboard to PCB After building a working prototype with a breadboard, I was wondering what's next.
So I read about integrating the arduino into a PCB layout.

But in my case, it's worth it? 

My project will use a Arduino Mega, futhermore some wired piezo switches therefore I need pcb connectors, and a small amount of resistor and transistors. 
I am considering to buy a Mega of the shelf and use the contactpins on a header to fix it on my PCB. Also probably fix it with some screws.

It will save me a lot of pcb design time (a maybe some mistakes) and it will save me buying all diferent components. The  ATMega2560 alone is already around 10,- 

I think I only need 10 or 15 pcb's, definitly no massproduction.

Your opinions...
I agree with Majenko's proposal for a proto shield, or if you need a "flat" design beside the Mega get yourself a striped (one /two sided and in different sizes) vero board (its like a breadboard to solder) 



You could even use Fritzing to design the most efficient layout for this option in regards to space/material saving or minimum solder points
