My recent Bernina service with "the best in the industry" (because he trains so many of the national repair people), on a 1031 that has not been serviced for 8 years, was less than $100. It came home purring, shiny clean inside and out, and with a mile on both our faces!
This machine is not computerized, that may have had something to do with it, but I can really make some fabulous quilts on it and he complimented me on it's daily care in my hands. So glad I knew to travel 4 hours to take it to him!
