I can drive past Circuit Specialists in Mesa, Arizona, almost every week.
They sell chemicals and photosensitive boards. I doubt they have the lowest
prices on the entire web but they are convenient and I pay no shipping.
Yesterday I was looking at their selection of boards. They had 3" x 5"
single sided boards for $6.64. That is 44.3 cents per square inch. But they
also had 4.6" x 6.6" single sided boards for $4.49. That is 14.8 cents per
square inch. The lower priced boards come from a variety of suppliers so I
figure they are getting rid of old stock. They sure have a lot of them.
