Another way to workaround that pretty cheap and reliable for a long time, and I was using for years: Tecco papers are always delivered with 3" to 2" adapters (simple flat plastic tubes). If you buy a Tecco sample roll (typically 5 meters) you will be done with around 20$ or even cheaper, depending on the paper you have chosen. At least in Germany Tecco offers this very nice service of paper samples on rolls, but this should be available everywhere Tecco paper is being sold I guess.
