I ordered another lot of 5 PCBs, again using JLCPCB as the supplier.  The total cost, including shipping was CAD $15.00 (USD $11.33).  This time the PCBs were manufactured with blue solder mask rather than black.  Order to delivery at my home was about 2 weeks.

For version 2 of the stripboard I made two improvements:

1.  On the top side, a grid was added to make it easier to count holes

2.  On the bottom side, white dots were added to the silkscreen indicating the direction of the stripboard tracks.  The dots are still a bit hard to see.  Using solid lines between the holes would be better... something for version 3.
