Here is a picture of the PCB's I made for the current sources and a few other googaws such as a 2.5 volt reference and a 5 volt to 7 volt switcher. The board is about 1.5" square and will have a 14-pin SIP connector soldered to one edge.
The panel was made by the toner transfer method. The smallest traces are 8 mils and most of the other small traces are 12 mils. I quit etching early since it is always easier to remove a short than to add a jumper.
