I recently bought a secondhand X-Rite 361T densitometer including the original calibration strip. I am now looking for a transmission density standard, like the Stouffer TP4x5-31 for film testing and some other experiments I want to run. I can buy one directly from Stouffer for 68.50 USD + 10 USD for standard USPS shipping. They do, however, take no responsibility for the parcel actually arriving here in the Netherlands. If there is a European seller, I'd be inclined to buy from them instead because of this. So far, I only found Asmetec, but their prices are twice of that of buying from Stouffer directly.

Does any of you know of a seller I might have missed? Or do you know a good alternative from another brand that is similarly priced?
