I got a PE770 4 yrs ago. I just brought it in for service. he tinkered with it for about 1/2 hr before going for the most expensive way. it needed a new bobbin case. he asked if I minded a NON-Brother part for $25 as compared to a Brother for $98. I took the cheap route. they didn't charge me for anything but the part. you won't get service like that from Home Depot.
