@Coding Badly and @larryd - nice links.
I researched both local and online pcb mfg not too long ago; the links I found were profoundly expensive for a prototype board (full of my many mistakes). As an alternative, I used my flat griddle iron to transfer the toner the dual clad pcb; results would vary due to the unscientific process. Disappointments were unnerving. Hence, I began searching for a more controlled environment for prototypes; T-shirt presses and the like. The T-shirt presses appeared flimsy and reviews were poor; instead, I found a heavy duty rosin press. Caution – you may appear on a list of the Revenue Commissioners and Criminal Assets Bureau of Ireland.
Obviously, if final production is the intent, my comment should be disregarded.
