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?
