I'm pretty sure me and the sales guy on the phone were talking about the same thing. I have to agree , for $7 my method isn't worth the trouble. I found that site you mentioned http://www.stouffer.net Wow, they make many dozens of these gauges. Did you get the uncalibrated 21 step transmisive guide (part # T2115) $6.10 ? I think that probably best all round choice, even though 21 steps is probably more than needed. If they send it in a standard envelope then I guess postage worldwide would be cheap too.
