Although I don't have a Juki, the dealer I go to, services the machines he sells, along with other machines. I go down once a year to have my Elna serviced, and he does me a huge service, because he gets it done in one day, since I travel 8 hours to get to him. Although, I do sometimes take 2 or 3 machines, he does get them done in 2 days. LOL He does a very thorough servicing.
