I've just started to learn how to make fresh pasta, and I absolutely love it. Problem is, it's a pain to roll out the dough by hand every time. I've been looking at pasta rollers, but a lot of them seem to be screwed into counters fairly permanently. For someone who moves around a lot, this would be terribly inconvenient. Are there any good pasta rollers that do no need to be screwed into a counter top permanently?
