I have a manually-operated pasta maker and have been using it for at least 20 years. The only thing I can recommend is that you purchase one that is already powered by a motor or can be retrofitted for one at a later time.
What I've discovered, as arthritis has become the norm for me, is that it's getting progressively difficult to operate my maker manually. I can purchase a motor for mine that will take care of that problem.
Best wishes with your search and have fun making pasta. I love mine.
