I have to take my serger in yearly. It costs $150 to $200 each time. I really run it to almost death. The cutting blade needs replaced + various other things. I use it mostly to do old levi pieces for Billie blankets. My old Singer (that only goes back & forward) gets serviced by ME! I have taken it apart several times & believe it or not-I get ALL the pieces back & in the right places. When ol'steady freddy singer decides to have a r&r without notice-I am really lost! I guess that I'll have to get that new/used one I got(that supposedly does embrodery, & figure out how to wind the bobbins. LOL
