I, too, have one....since 2000.Paid $999.00 on sale. It is my definite "go to" machine for straight stitching...Very uncomplicated.....Have you contacted Brother to see if you can't buy a manual? Bet you can although if you are a stitcher, you will figure this out in no time. As for bobbins, the manual says Part # SA159. I get mine on line or at a local quilt shop that also does maintenance. This machine does require sewing machine oil often and rather diligent lint removal. I even take the bottom off my machine every six months and clean out the lint. As a result, I've only taken it in for a full maintenance twice since I've had it. I generally put one drop of machine oil in each of the little holes on top of the unit, under the throat and one drop on the "hook" of the bobbin. I do think the threader is worthless. I just thread mine manually. This is a workhorse and a very well built machine. Glad you found yours.....
