I currently work on a tiny Rondo STM513 that needs new belts soon. I am seeing both canvas and vinyl options. I've always only worked on canvas, and while I like it, it does get inherantly grimy over time. I am curious about the vinyl option but can't find any reviews. Has anyone worked on both that has any insight? Most of what we do on it is cookie dough and pie dough, so lots of buttery goodness!
