You got a great deal! I paid $50 for mine (no cabinet), and dh replaced a spring in the bobbin winder area for me. I purchased a foot for doing fmq and did quite a few oiling sessions to loosen the screw to lower feed dogs. It's ready to go. As soon as I finish the quilt I'm working on, I'll do a project with my 15-91 to really get to know the machine. Didn't want to switch fmq'ing to a different machine half way thru in case it didn't go well! Enjoy your's.
