this lot includes a Pfaff 7550. I've been sewing on a 20+ year old Babylock which I like (I think I like it, LOL, as I don't know anything different).

I bought my 7570 brand new and mine cost about $3,300. The 7550 is just below mine and I LOVE my machine and got it because of the on-board walking foot. It is all metal inside and that is a very good thing, mine stays at home due to the hefty weight. That sounds like a good price, look at and 'lift' other machines in that price range. Mine has never given me a minute of problems and if it has been gone through, you should be fine to buy it. The service charge could be $100.
Let us know what you decide and if you got some fabric.

I have a Pfaff 7570, which is just like the 7550 except for a few upgrades. I have had it for about 7 or 8 years, and love it. We bought it used for $1,000, and INHO $500 is a fair price for it, as it is a great machine. It is my go to machine. I do have 2 newer machines, but my Pfaff is my specialty. Go for it, you won't be disappointed. I love mine.

Sounds fair to me. I would be drooling over the fabric. Welcome to the board!

The 7570 was the last machine made in Germany I've been told, and I just love mine. I plan to keep it until I die.

I inherited a 7570, but I did not love it as I thought I would. I prefer my even older Bernina, although I do most of my sewing on a TOL Babylock now. The few things that I did not like about it - had trouble with the bobbin winder, just couldn't quite get it figured out but that is likely operator error. But mostly, it seems as if the bobbins just didn't hold much thread - always changing them out. As a new quilter, I became drawn to a machine with a larger harp space very quickly. I also had a lot of trouble with the leading edge of the fabric getting chewed up in the feed dogs. I know how to prevent it, but had never had the issue with my Bernina of a similar vintage.

back to expensive fabric...you are right. Just be selective that what you do buy, you purchase it because you love it and NOT because it was too cheap to pass up. That second kind of fabric will go into your fabric crypt and you'll hate it every time you see it.
I inherited two stashes, and both women had wonderful taste...but it wasn't my taste and about 80% went to new homes.
The other stuff in the ad? As your interest and skill grows (as with any interest) you will know when you need certain tools. Wait.

Welcome to the board, and good luck with your question. I will watch with you to see the replies

Wow, I almost bought one years ago. Pfaffs are great machines. -- but I don't think 500$ is a bad price. I would try to bargain of course -- You won't be disappointed.....shame it isn't closer!

OMG!!!!! YES - I have a Pfaff and the 7550 is a GREAT machine (it's older, but still a work horse). Most of the time that machine starts off in this area at $800.00 and goes up. I would do it it a heart beat, but you've been using another machine. So I would say, take something small over and sew with the machine. It should be quiet and smooth. It should also have a walking foot (you will love that). This Pfaff was made in Germany, when the Pfaff family still owned the company. Now hey are made in Japan (not the same). Good luck
