A real workhorse machine is the older Bernina 830. It is a mechanical machine rather than computer. I had mine for 30 years and it was heavily used. I finally sold it to a friend but still miss it. It never gave me a problem and was simple to use. They can be found on Ebay and Bernina stores. They are all metal construction. Beware of the low cost machines of any brand that are mostly plastic and nylon parts because they warp with heat and can never be repaired properly. If you choose a used or refurbished machine you most often get a lot of feet and attachments which is a big plus. I am amazed at what new feet cost!
