I recently posted about finding ours at an estate sale for $20. I didn't realize it was a Centennial til I got it home. I took it to the shop and paid $65 for a tune-up, belt, and inspection, and paid ~ $20 for the fantastic FW book. I also bought a 1/4" foot for $17. Our FW doesn't have a case, and the only feet we have are the original and the 1/4", but we love the machine and it makes a nice straight stitch. I can't say I would use it every day because the size is a bit of a challenge, but for $20 it's a great back-up machine, and it does travel well.
