Stouffer offers a variety of transmission step wedges as well as reflection step tablets for prints. You'll have to decide how many steps you want and what format is desired. 21-step (1/2 stop increments) is common, but I prefer 31-step (1/3 stop increments) as it provides more data for smoother characteristic curve plots.
Haa you're facing the minimum order problem aren't you...
I bought a few extra last time so it's nothing to me...
For $7.50 donation to APUG, I'll send you a T2115...
I'll "calibrate" it for you too... (Basically I'll read it with my densitometers and write down what they say, not NIST-traceable but better than not having numbers)...
