I remember some discussion here about a year ago about inexpensive step
wedges. I'm looking at Bostick & Sullivan's page and the calibrated one costs
$19 (uncalibrated $8). Is there still a less expensive alternative available?

What is the practical difference between the two mentioned above? Could I
produce something myself cheaper?
