The OP has discovered that she has a 101. It's noisier than the 201, but not difficult to find parts for if you want to get it running. It's a good, strong machine, but it's not particularly sought-after by most collectors or quilters - I don't know very much about 101's, but I do know that people who have several different models prefer their 201's or 15's to the 101 - I can't remember which features it's missing compared to the others. Reverse and droppable feed dogs, maybe?
Personally, I would buy a 15-90 or 15-91 and put that in the 101's cabinet. The 201 is great, and probably the quietest electric sewing machine ever made - I LOVE them! But the bobbin is smaller which requires much more frequent bobbin changes while you're free-motion quilting and with the bobbin being horizontally oriented, you may have more skipped stitches than with a vertical bobbin.
The 15 will power through anything without any trouble at all, there's a lot of room under the arm, (I've quilted king-sized quilts in mine) it takes standard 15x1 needles and class 15 bobbins and replacement parts are cheap and easy to find. I've had Jenny at sew-classic.com rewire the motors for me and I buy replacement lights, cords and foot controls for all of my 15's and 201's.
The 15's are so plentiful that if you can't find a really nice one for $50 or less in under a month, I'd be shocked. Spend $50-100 on the machine and another $150 on the electrics and you've got a machine that will do anything you ask it to. You can buy huge assortments of attachments for very little and those attachments are what make your straight-stitch machine versatile. I love the rolled hemmers, the gatherer and the flat-felling feet.
I use my 15's for 99% of all my sewing - in conjuction with the serger, I can do anything.
