I have a Lilly 550 that is about 11 years old and I love it. It sews so smooth and never had any problems.

Have the Designer 1, bought second hand a couple of years ago...great machine, love that I can do embroidery too.
Have the Pfaff for patchwork piecing though love the IDT walking foot.
If the Husqvarna had an integral walking foot would be the best machine on the market !!!!

Love my Sapphire!

I have Husquvarna Rose, Designer I, 905 Serger and a 910 serger I love them all (would love the new designer diamond)
I also have a Janome Gem that I take to classes and on vacation love that too

I love mine it is from 87 and has never been in the shop the shop I go to to get feet said that the older ones are work horses

I have had mine for several years and really enjoy it!

I started with the Plus One 30 years ago. Then a few years ago I bought a Sapphire 850 then up graded to a diamond 3 years ago. I never want another machine. It is perfect . they have come up with a new diamond that is an upgrade to mine. Haven't seen it yet but it can't be bad. I would buy mine again in a second.

Do a search here on SVP using the button above.( the Singer Viking Pfaff buy-out). There's lots of info. on those threads.

I have the Viking Mega Quilter and I just love it. Do all my FMQ on it. I wanted one to do the fancy stitches and simple blanket stitch so I bought the Sapphire. I hated that machine from week one. I just sent it to my sister who's machine died and she can not afford to buy one. I picked up an old Singer 401 for the fancy stitches and I love it, love it.

take a test drive ~ I have the quilting Sapphire 850 and wouldn't trade it for the world... then I also have the Designer I ESS embroidery, which is about 2 models before the Diamond. Love it, its been a workhorse since 2002 for me!
