I bought the 1011 a few weeks ago. It is a wonderful machine that purrs. I made my KwikSew jeans with it. I bought one of these a few years ago, but it was packed horribly and arrived smashed. With eBay's help, I received a full refund.
The 1011 has a beautiful stitch and is quiet.
The 1001 has a rotary hook. It is really quiet and makes a beautiful stitch.
The third, but the one I was most anxious about is a Bernia 1120, a computerized machine. It was advertised on eBay as parts or repair, but the seller did say it powered on and the needle went up and down. I decided to take a chance for the price. Especially since the extension table and the case were included.
What a honey! The 1120 is so smooth and quiet with a beautiful stitch.
The fourth is one I have wanted for along time. It is a 910. Just like the famous 930, but with a blue face plate and fewer decorative stitches. It was also on eBay as parts or repair.
Smooth doesn't even start to describe this machine. It also has needle up/down by tapping the foot pedal.
I also have several other vintage Berninas.
Ugh! I think my SMAD(Sewing Machine Acquisition Disorder) has just turned to BAD(Bernina Acquisition Disorder).
Hopefully my BAD will be in remission for a while now.
Thanks for stopping.
