Thanks for all the suggestions. I am keeping a list.
Miriam, Since you repair, do you have a recommendation for a machine? Looking for a good, fairly basic, portable, mechanical (I think?), reliable machine with a sturdy base and a front surface piece. I don't really like not having an extra surface in front. My dad can repair the mechanical machines, that's why I am looking at goodwill as well as everywhere else. Any underrated ones that would be less expensive? I'd rather find one that is under 45 years old or so.
Thanks for all the help!!
