John,
You are telling me you can't find a board shop to do two sided 4"X6 with
through plated holes and solder mask and silk screen (one side) for
$15...... Well I just made 30 boards 5"X6" with all that, and 19 IC's
(8x28pin 8X14pin 3x3pin) my cost $10.00 includes artwork tooling and
setup fee. No extra charge for different size drills....
How many of these 4X6 are you planning to make ? I can get you a price.
